An unsigned out-of-tree module must be loadable — i.e. no Secure Boot / +# module-signature enforcement. `mokutil --sb-state` is captured in the +# preflight for exactly this. +# 3. systemd must be running, because setup.sh writes unit drop-ins under +# /run/systemd/system and starts mhvtl.target.

Design notes worth knowing + +**The refusal lives in the orchestrator, not the CLI.** `TapeOperationOrchestrator` +is this codebase's single choke point for moving media, so `IMPORT`/`EXPORT` +became op types there and the guard sits inside `_export`. Anything that reaches +the orchestrator is guarded, including `POST /tape-ops/execute`. It fails +**closed** on a catalog-less repository: an unknown payload is not an empty one. + +**`MOVE` still refuses I/E destinations.** Defect 3.9 (an unvalidated +`dest_slot_id` ejecting a cartridge holding 358 archived files) stays closed — +`_dest_slot` rejects import/export elements exactly as before. The new op types +are the only way to reach the mailslot, and they carry their own guard. There is +a regression test for this. + +**The first draft of those op types reopened it anyway, and an adversarial +review caught it.** `_guard_export` assessed `request.barcode` while `_export` +moved whatever was in `request.slot_id`; `POST /tape-ops/execute` binds both +from the request body, so naming a blank cartridge and pointing `slot_id` at a +loaded slot ejected the wrong tape past a guard that had just said "carries no +data". Two siblings of the same shape came with it: `ie_slot` reached +`mtx transfer` with no validation at all, and the catalog `exported` flag was +written only by `MailslotService`, so the API path moved media and left every +restore believing the data was online. All three are closed — the source slot is +resolved from the barcode and `slot_id` is only a cross-check; every element +number is validated against the library's own elements; the catalog write lives +beside the move. Worth stating plainly: *the fix for defect 3.9 did not +generalise to a new code path, and only an attack on the API surface found it.* + +**The guard is mutation-checked** — five mutations, each restored byte-for-byte: +delete the `carries_data` refusal (4 tests fail), make the catalog-less branch +permissive (1), re-trust `request.slot_id` in `_export` (1), drop the `ie_slot` +element validation (1), drop the catalog state write (4). + +**Export writes `cartridges.state = "exported"`.** That flag was read by +`jobs/restore.py`, `jobs/sharded_restore.py` and `jobs/archive.py` and set by +nothing outside a fixture, so media leaving the library used to leave the catalog +claiming the data was online. Import clears it. A unit test demonstrates the +whole consequence chain: export → `run_restore_job` raises `CartridgeOfflineError`. + +**A cartridge in the mailslot is still `CartridgeState.IN_SLOT`** at the library +layer — it is inside the machine until a human opens the door. Whether its *data* +is online is the catalog fact above. `find_slot_by_barcode` does not see it, so +nothing can load or unload to it by accident. + +--- + +## 4. Still true after this work (do not assume otherwise) + +- **Per-file load/unload remains.** `restore tree` reuses `run_sharded_restore` / + `run_restore_job` verbatim rather than reimplementing the loop, and those load + and unload around each file. Grouping the plan by cartridge keeps one tape's + files consecutive, which helps locality but does **not** remove the swap. The + campaign runbook's "1,073 restores produced ~1,073 load/unload pairs" still + describes the cost; fixing it means a batching restore session in the service + layer, which is a separate piece of work. +- **Sharded archive catalogs files under their absolute source path**, not under + `//…` the way `run_archive_job` does. So the prefix for a + `restore tree` of sharded content is the source directory + (`restore tree /data/photos`), not `/photos`. This is existing + `run_sharded_archive` behaviour, identical through the API; the CLI wraps it + rather than changing it. Worth unifying, deliberately, at some point. +- **`--lanes N` often finds nothing on a fresh volume group.** + `run_sharded_archive` links a lane cartridge to the volume group only when the + cartridge row does not already exist, so media the catalog already knows about + never joins the group. `--lane-barcode` (repeatable) is the reliable form and + the error message says so. Again: identical on the API path. +- **Restore-to-a-directory basename collapse** is unchanged in the *single-file* + paths. `restore tree` avoids it; `openblade restore --path … --to ` does + not. +- **A catalogued record with nothing archived is reported, not restored.** A + failed archive leaves exactly that shape; the summary carries `filesSkipped` + and `skippedPaths` and the CLI says so on stderr, because a tree that silently + comes back short is the failure this command exists to prevent. +- **`--force` is still a plain flag, not a two-phase token.** `openblade format` + requires a dry-run plan plus a one-time `SafetyToken`; export does not, and an + API caller can pass `extras: {"force": true}` as a bare JSON boolean. Export + destroys *availability* rather than data, and the operator is shown exactly + what is on the cartridge first — but the asymmetry with FORMAT is deliberate + only in the sense that nobody has decided otherwise. Worth a decision. +- **`docs/wiki/reference/cli.md` is stale on this branch** and + `tests/unit/test_wiki_reference_generated.py` is red because of it. The page is + a build artifact of `tools/gen_wiki_reference.py`; regenerating it is owned + elsewhere and these commands will be picked up then. + +--- + +## 5.

The repo's `SAMPLE_MTX_LOADED` uses the tight form on its +drive line, which is why unit tests never caught it. + +This would have fired on the i3 the first time a tape was loaded. Fixed; regex +now tolerates optional whitespace. + +### 3.2 `mtx.py` — import/export slots silently dropped + +`_SLOT_RE` matched `Storage Element (\d+):`, which does not match +`Storage Element 9 IMPORT/EXPORT:Empty`. All four I/E slots vanished from the +inventory, leaving `len(status.slots) == 8` while the header said 12. A tape in +the mailslot was invisible. + +The bring-up plan flags i3 I/E slots as a likely regex divergence (Phase 3.4). +It was right. + +**They are parsed into a separate list, deliberately.** The obvious fix — put +them in `slots` with an `is_import_export` flag — is wrong, and adversarial +review caught it before it shipped. `SlotState` carries no such flag, so the +distinction is erased at the `library.py` boundary and every consumer would +suddenly see 12 slots where it saw 8. The sharp edge is +`routes_aml_move_medium.py::_first_empty_slot()`, which returns the first +unoccupied slot: on a full library — the normal state of a production +library — the first *empty* element is the operator mailslot, so an unload +would eject the cartridge to the front panel. `routes_aml_library.py` would +also have double-counted I/E slots in `slotsTotal`, on a parity-gated AML +response. + +So `MtxStatus.slots` stays "data storage slots", `MtxStatus.import_export_slots` +holds the mailslot elements, `all_slots` merges them for anyone who wants both, +and `slot_count` (the header figure) equals the two together. Nothing +downstream changes behaviour; the information simply stops being discarded. + +### 3.3 `ltfs.py` — `device_list()` could never succeed + +Three independent problems, all invisible without real LTFS: + +- `ltfs -o device_list` writes its **entire output to stderr**; the code parsed + `result.stdout`, which is empty. +- It **exits 1 even on success**; the code called `raise_on_error()`, so the + method raised unconditionally. +- The real output format is + `Device Name = /dev/sg1 (14.0.1.0), Vendor ID = IBM, ... Serial Number = OBLADE_D01`, + nothing like the fictional `LTFS14001I 0: /dev/st0 (...)` sample the regex was + written against. + +Fixed: parses stdout+stderr, judges success by whether devices were parsed, and +handles both formats. `LTFSDevice` gained a `serial` field — see §4. + +### 3.4 `ltfs.py` / `discovery.py` — LTFS was given the wrong device node + +The LTFS `sg` backend addresses drives as `/dev/sgN`. `library.py` supplies +`/dev/stN`. Handing LTFS `/dev/st0` does **not** produce a clean error — it +reads the wrong device and reports: + +``` +LTFS17016E Cannot parse index direct from medium (-21700). +LTFS11253E No index found in the medium. +LTFS11027E Cannot mount volume: medium consistency check failed. +``` + +which reads as *blank or corrupt media*. On the i3 that is a support incident +where the operator concludes the cartridge is bad. + +Added `discovery.resolve_sg_device()` — reads the mapping from +`/sys/class/scsi_{tape,changer}//device/scsi_generic/` — and applied it in +`format_tape`, `mount_readonly`, `mount_readwrite`. **The mapping must be read, +not derived:** `st` and `sg` numbers are allocated independently, and this rig +routinely produces `st0 -> sg1` and `st2 -> sg4`. + +### 3.5 `ltfs.py` — unmount returned before the drive was released + +`umount` returns when the kernel detaches the filesystem, but the LTFS FUSE +process lives on briefly to flush its index and close the drive. Until it exits +the drive's sg node is held, and the next mount fails: + +``` +LTFS30210I Cannot open device: failed to open /dev/sg2 (16). # EBUSY +``` + +Any unmount→remount cycle hits this, and on a real library so does +unload→reload. Added `wait_for_ltfs_release()` (polls procfs, bounded 60 s); +`unmount()` now waits and reports `device_released` in its result details. + +### 3.6 Test-side defects — `sg_inq` on a rewinding node, and `--tape-serial` + +Two bugs in `tests/hardware/` helpers, both of which would have produced false +failures against the i3: + +- `_resolve_scsi_path()` normalised `/dev/nst0` → `/dev/st0` for matching and + then **returned the rewinding node**. `sg_inq /dev/st0` exits 50 + (`close error: No medium found`) whenever the drive is empty, because closing + a rewinding node attempts a rewind. The inquiry itself succeeds — the command + still reports failure. Drives are empty most of the time, so this was a + guaranteed false failure. Now prefers the sg node. +- `_format_tape()` (duplicated in `test_ltfs_operations.py` **and** + `test_performance.py`) passed the barcode as `--tape-serial`, which takes + **exactly 6 alphanumeric characters**. Real LTO barcodes are 8 (six plus a + media-type suffix like `L8`), so this failed every time with + `LTFS15029E Tape serial must be 6 characters.` The barcode belongs in + `--volume-name`, which is what the product code already used correctly. Both + copies fixed. + + *The duplication is the underlying smell:* two hand-rolled copies of the LTFS + invocation in two test files, both diverging from the product's own correct + version. Worth collapsing onto `LTFSCommandBackend` later. + +### 3.7 `validation.py` — `device_list_ok` was always false + +Found by running the Phase 4.1 command against the rig. `validate_ltfs_capabilities` +computed: + +``` +device_list_ok=any(current.device == device for current in devices) +``` + +`devices` comes from LTFS, which only ever lists `/dev/sgN`. `device` is +whatever the caller named — and the CLI help for this very command says +*"Tape device path such as /dev/st0"*, while Phase 4.1 of the bring-up plan +passes `/dev/nst0`. The two can never be equal, so the report said: + +```json +{"discovered_devices": [ ...three healthy drives with serials... ], + "device_list_ok": false} +``` + +A false alarm at the first gate of the bring-up, on a working library, with +the contradicting evidence printed directly above it. Fixed by resolving both +sides to their sg node before comparing. Verified against the rig with all +three spellings — `/dev/st1`, `/dev/nst1`, `/dev/sg2` — all now `true`. + +### Regression tests + +Every fix ships with one. Parser-level tests live in +`tests/unit/test_hardware_parsers.py` (`TestMtxParserAgainstRealOutput`, +`TestLTFSParserAgainstRealOutput`, `TestResolveSgDevice`); the command-level +ones — which argv is actually built, and how `device_list`/`unmount` behave — +live in `tests/unit/test_hardware_safety.py` against a `RecordingRunner`. + +They are anchored on byte-accurate captured output (`SAMPLE_MTX_REAL_SCALAR`, +`SAMPLE_LTFS_DEVICE_LIST_REAL`) rather than on hand-written samples, which is +precisely how the original bugs hid. + +**All were mutation-checked** — each fix reverted, the expected tests confirmed +to fail, then restored: + +| Mutation | Tests that failed | +|---|---| +| tight `VolumeTag=` regex restored | 1 | +| I/E-blind slot regex restored | 3 | +| `resolve_sg_device` → naive name derivation | 5 | +| real-format branch removed from LTFS parser | 4 | +| `resolve_sg_device` dropped from the 3 LTFS call sites | 4 | +| `device_list` back to `stdout` + `raise_on_error()` | 1 | +| `unmount` judging success on the umount exit code | 2 | +| unreadable `/proc` treated as "released" | 1 | +| `device_list_ok` back to raw string equality | 1 | + +The last four exist **because** the first mutation round was not enough. The +initial pass only mutation-checked the *parsers*; adversarial review pointed +out that the plumbing around them — the three `resolve_sg_device` call sites, +`device_list`'s stderr handling, the unmount gate — had no test that would fail +on revert. It also caught a genuinely vacuous assertion: `assert +wait_for_ltfs_release(...)` in the hardware tests passes against a stub that +returns `True` unconditionally, since with no LTFS running the real function +also returns `True` immediately. That is the "returns `[]` for a blocked URL" +pattern the project rules call out by name. + +--- + +### 3.8 What adversarial review changed + +Worth recording, because two of these were fixes that *worked* and were still +wrong: + +- **I/E slots in the inventory** (§3.2) — reshaped from "flag them" to "keep + them in a separate list", because the flag was erased downstream and would + have made the AML unload route eject cartridges to the mailslot. +- **`format-scratch.sh` matched barcodes by substring.** `find_slot()` used an + unanchored `index($0, want)`, so `format-scratch.sh OB0008L8 ""` formatted + the requested scratch tape *and then* `OB0001L8`, a data tape — the empty + argument matched the first cartridge in the library. It also never checked + what was actually in the drive before running `mkltfs`. Now: barcodes are + validated as well-formed, matched against the whole VolumeTag, and the drive + is re-read after loading so the **loaded** cartridge's VolumeTag must equal + the requested barcode before anything is written. That last step is the + "positive barcode confirmation" AGENTS.md requires; the first two only decide + what to load. +- **`reset.sh` unloaded drives without checking for a live LTFS mount** — + directly against "never unload while LTFS is mounted or dirty", in the one + new script that issues unloads, and worse because it exists specifically to + clean up after *failed* runs, which is exactly when a mount is left behind. + Both it and `format-scratch.sh` now refuse and tell you how to clear it. +- **`unmount()` computed `device_released` and discarded it** — callers marked + the drive `UNMOUNTED` regardless, so `can_unload_drive()` would green-light + an unload with LTFS still holding the drive. The wait was a 20-second pause + that changed nothing. Success now *means* the drive is free. +- **`wait_for_ltfs_release()` failed open** — an unreadable `/proc` (hidepid, a + container, a different uid) read as "released". For a gate protecting an + unload, "I could not look" must not mean "safe". +- **Scripts selected the changer as "first `mediumx`"** — Phase 3 cables a real + i3 to this same host, a real HBA usually enumerates below mhvtl's dynamic + host number, and a real Scalar i3 reports the same `QUANTUM` vendor string. + They now key on the rig's unit serial and refuse to guess. +- **`setup.sh`/`teardown.sh` were not as well-scoped as their comments claimed.** + `/etc/mhvtl` and `/opt/mhvtl` are mhvtl's own defaults, not paths this rig + invented. Setup now backs up a pre-existing config before overwriting it and + moves `library_contents.30` aside rather than deleting it; `--purge` removes + only the media barcodes named in our own `library_contents.10` and restores + the backup. +- **`MHVTL_REF` defaulted to `master`** — the patch is byte-exact against one + commit and the results here are from that build, so it is now pinned to the + full SHA. + +--- + +## 4. Suspected bugs in files owned elsewhere — NOT fixed here + +`openblade/hardware/library.py` and `sg.py` are owned by a parallel agent, so +these are reported rather than changed. The two `library.py` findings both +concern `_ordered_drive_devices()`. + +**(a) It returns the REWINDING `/dev/stN` node.** It prefers `block_device` over +`sg_device`, and `lsscsi` reports `/dev/st0` in the block column. Every consumer +of `drive_device()` therefore gets a rewinding node. This is the direct cause of +§3.4, and Phase 0.3 of the bring-up plan explicitly calls LTFS-on-a-rewinding- +device a corruption footgun. `ltfs.py` now defends itself with +`resolve_sg_device()`, but the source should prefer `sg_device`, or at minimum +the no-rewind `nst` node. + +**(b) Drive ordering is assumed, and the assumption is fragile.** It sorts by +`(host, bus, target, lun)` and indexes by `drive_id`. On this rig that ordering +is **correct** — verified by serial: changer Data Transfer Element 0 is +`OBLADE_D01` at `[14:0:1:0]`, which is the first row in SCSI-address order. + +But it is correct by luck of mhvtl's config ordering, and the *device names* +around it are not stable at all. Across reboots of this same rig: + +| boot | target 1 | target 2 | target 3 | +|---|---|---|---| +| A | `/dev/st0` | `/dev/st1` | `/dev/st2` | +| B | `/dev/st2` | `/dev/st1` | `/dev/st0` | +| C | `/dev/st1` | `/dev/st2` | `/dev/st0` | + +So sorting by SCSI address is defensible and sorting by device name would be +actively wrong — but neither is *verified*. Phase 2 of the plan asks for exactly +this to be proven with ≥2 drives, and the honest answer is: **the ordering +happens to hold on mhvtl, and nothing checks it.** Recommend correlating changer +elements to drives by **serial number** (`sg_inq`, or the new `LTFSDevice.serial`) +and failing loudly on mismatch, before the first multi-drive write to the i3. +`scripts/mhvtl/setup.sh` now prints the correlation table on every run. + +### `sg.py` — `parse_sg_inq()` reports every real device as `unknown` + +Also owned elsewhere, so reported not fixed. `_DEVICE_TYPE_RE` (sg.py:19) +matches `Device type:`, which is what the module's `SAMPLE_SG_INQ` contains. +Real `sg_inq` (sg3_utils 1.x) prints something else: + +``` + length=36 (0x24) Peripheral device type: medium changer + Vendor identification: QUANTUM + Product identification: QUANTUM Scalar +``` + +`Peripheral device type` does not match `Device type` (lower-case `d`), so the +regex never fires and `device_type` falls through to its `"unknown"` default — +for **every** device. Vendor, product and revision parse correctly, so this is +easy to miss. + +Two things need fixing together: + +1. the label — accept `Peripheral device type:` as well as `Device type:`; +2. the value — `[^\s]+` would capture only `medium` from `medium changer`. The + type is a multi-word value and needs to be read to end-of-line. + +Impact is diagnostic rather than functional: `ScsiInquiry.device_type` is not +used for any decision, only surfaced in the `connect-i3` report. But that +report is precisely what an operator reads during bring-up, and it currently +labels every device on the bus `"unknown"`: + +```json +{"device": "/dev/sg4", + "inquiry": {"device_type": "unknown", "vendor": "QUANTUM", + "product": "QUANTUM Scalar", "revision": "0108"}} +``` + +--- + +## 5. Where this would block on a different host + +The rig needs all of these; each fails loudly with a specific message from +`setup.sh`: + +| Requirement | Failure if missing | +|---|---| +| `linux-headers-$(uname -r)` for the **running** kernel | kernel module build fails | +| Secure Boot disabled | `modprobe mhvtl` fails — unsigned out-of-tree module | +| Real host, not an unprivileged container | module cannot be loaded from inside | +| root | `/etc/mhvtl`, `modprobe`, `/dev` nodes | +| `mkltfs` / `ltfs` | LTFS/archive/sharded/performance suites do not run; the rest do | + +`setup.sh` is idempotent and `teardown.sh --purge` returns the host to a clean +state, so a failed attempt costs nothing. + +--- + +## 6. What this phase did *not* prove + +Being honest about the limits, since the point of a rehearsal is to know what is +still unrehearsed: + +- **TapeAlert and drive diagnostics.** 5 skips. mhvtl does not emulate these log + pages; `openblade/hardware/` code that reads them is still unexercised. +- **Robotics timing and failure modes.** mhvtl moves media instantly and never + jams. The barcode-reader lag noted in the LTO-7 quirks section, load timeouts, + and retry paths cannot appear here. +- **Real element addressing.** The rig uses the Scalar personality's element + addresses deliberately, but `mtx` normalises them to 1-based logical numbers + before OpenBlade ever sees them. Phase 3.4's "diff real `mtx status` against + the samples" is still required at the i3. +- **Media compatibility, LTO generation rules, cleaning cycles, WORM.** +- **Control-path/LUN-1 bridging** — the "no `mediumx` appears" failure mode from + Phase 1 is structurally absent here. +- **Dirty-unmount recovery**, which needs process control beyond `SafeRunner`. + +Phases 3 and 4 stand unchanged. What this phase removes is the class of failure +where the *parsers and device plumbing* are wrong — and it found seven of those. diff --git a/docs/runbooks/real-data-campaign.md b/docs/runbooks/real-data-campaign.md new file mode 100644 index 0000000..6cc83f3 --- /dev/null +++ b/docs/runbooks/real-data-campaign.md @@ -0,0 +1,747 @@ +# Real-data campaign — the first pass through the operator surfaces + +**Date:** 2026-09-11 · **Rig:** the mhvtl rehearsal library from +[`docs/runbooks/mhvtl-rehearsal.md`](mhvtl-rehearsal.md) — 1 QUANTUM Scalar +changer, 3 IBM LTO-8 drives, 8 storage + 4 I/E slots, real LTFS 2.4.8.4 +· **Backend:** `OPENBLADE_BACKEND=real` + +The rehearsal proved the *parsers and device plumbing* work.

The campaign dataset happened *not* to trigger this (its names +are globally unique), so it was reproduced deliberately; that is worth noting, +because a dataset with per-directory naming (`2026-01/report.pdf`, +`2026-02/report.pdf`) hits it immediately. + +`_stripe_tape_path()` now mirrors the source tree under `/stripe`, the way the +non-sharded path already mirrors it under the volume group. Re-verified on the +rig: `/stripe/alpha/same.txt` and `/stripe/beta/same.txt`, both restoring to +their own bytes. Existing media are unaffected — restore reads +`file_instances.tape_path` as stored rather than recomputing it. + +Self-review of that fix then found two defects *in the fix*: `Path.relative_to` +does not normalise, so a `source_path` of `/data/..` (operator-supplied, straight +from the API body) produced `/stripe/../etc/passwd` and escaped the mount; and +`relative_to(itself)` returns `Path(".")` rather than raising, collapsing a +single-file source to a bare `/stripe`. Both are closed — normalised lexically +with `os.path.normpath` (never `resolve()`, which touches the filesystem and +follows symlinks) plus a component filter. Worth recording because the +single-file case had a test that *passed* on the broken version: MockLTFSBackend +accepts any path string, so only probing the function directly exposed it. + +`tests/integration/test_sharded_archive_restore.py` · commits `7c041a5`, `441c11e` + +### 3.8 A failed sharded archive recorded no reason anywhere + +The first full sharded run wrote **3 of 1,073 files in ten minutes** and surfaced +as `failed_recoverable` with `error: null` and not one log line in 4,299 lines of +server output. `errors` was collected per batch, returned in +`ShardedArchiveResult`, and discarded by the API route (which answers +`{job_id, status:"pending"}` regardless); `update_job_state` was called without +an error argument, and the per-batch `except` had no logging at all. + +The handler now logs with a traceback, and a bounded, de-duplicated summary is +persisted on the job.

Every file on it became unrestorable +("Barcode not found in inventory"). **One unconfirmed integer orphaned a third of +an archive.** + +Moving media out of the library is an export, and the product's position on +export is already explicit — `routes_aml_move_medium` rejects moveClass +import/export on i3/i6 with 422.

It also calls `confirmation.validate(barcode)`, so + a token issued for one cartridge cannot format another. +- `POST /ltfs/format` now goes through `FormatService.confirm`, which checks the + persisted one-time token from the dry-run. **This is a deliberate contract + tightening**: the route previously ignored the `safetyToken` its own callers + were already sending (`tests/i3/test_07_ltfs.py:53` sends one), and formatted + on `confirm: true` alone. It now returns 422 without a token and 403 on a bad + one. `tests/i3/test_07_ltfs.py::test_format_with_timing` sends a placeholder + token and will need a real dry-run token; that suite needs a live emulator and + was not run here. + +While in `routes_ltfs.py`: `/ltfs/mount` and `/ltfs/unmount` returned +`str(exc)` from a bare `except Exception` on an unauthenticated route, leaking +argv, device paths and raw LTFS stderr.

In both, `statvfs` reads +the host filesystem — and `jobs/archive.py:255` copies that straight onto the +cartridge row. The reviewer reproduced it: + +``` +capacity_bytes: 1965172678656 used_bytes: 674029903872 ← the host disk +``` + +A ~2 TB "LTO-8 cartridge" in the catalog means spillover never fires again — the +exact bug 3.5 exists to fix, reintroduced from the other direction. And on a +nearly-full host disk, `remaining == 0` makes the new `_has_room_for` guard +refuse *every* tape. + +`_is_distinct_mount()` now compares `st_dev` against the parent's before +believing the numbers, and **fails closed**: if either stat fails, the answer is +no.

They now also assert `drive_at_format` and that + the cartridge returns to its **original** slot, and all three fail on a full + revert. The runbook's "every test was mutation-checked" claim was true of the + reverts I ran and false of the one I did not. +- **`test_default_config_keeps_home_relative_paths` failed inside the campaign's + own documented shell** — the fixture cleared only the two backend variables, + while `scripts/campaign/env.sh` exports `OPENBLADE_DB_URL` and friends. Fixture + widened. +- **A flaky capacity assertion.** `used_bytes` was asserted as an equality + against a live host filesystem, so a parallel test writing a temp file moved + `f_bavail` between the two reads. It is now a range, and the arithmetic tests + stub the mount check rather than depending on it. +- **One tracked `.pyc` was committed** in `bffd191` and has been restored. 66 are + tracked on `master` despite `.gitignore` covering them, and they are + `cpython-310` artefacts on a repo pinned to 3.12 — worth a `git rm -r --cached` + pass that is out of scope here. + +### Review findings NOT fixed + +Reported rather than changed, because each is pre-existing, sits in a risky area, +and the campaign had already made enough changes there: + +- **`jobs.error` now carries raw exception text at an unauthenticated boundary.** + `GET /jobs/` and `/jobs/{id}` have no auth dependency, and 3.8's error summary + routes `str(exc)` — which for a `CommandError` is argv plus raw `mkltfs` stderr + — into that field. `archive.py:333` already did this; 3.8 widened it. The right + fix is a sanitiser shared with `_safe_error_message`, and the existing test only + asserts the field is non-empty, so it locks in the leak. **This one should be + fixed before merge.** +- **`_has_room_for` only rejects a tape with *exactly* zero bytes free.** The + stated cause is LTFS index overhead, so the threshold should be a reserve, not + 1 byte; a tape with 512 bytes left still ENOSPCs on an empty file. +- **`RealLTFSBackend._tapes` is never hydrated from `cartridge.capacity_bytes`.** + After a restart every tape reports the fictional 12 GB default again, so spill + selection is wrong until each tape has been mounted once. The catalog already + holds the measured value. +- **`_format` takes the wrong drive lock** when `request.drive_id` disagrees with + where the cartridge actually is, and `RealLibraryBackend.unload` has **no** + `can_unload_drive` guard at all — the "never unload while LTFS is mounted or + dirty" non-negotiable is enforced only in the simulator. That is a real gap in + the product, not in this branch. +- **A failed unload in `_format`'s `finally` masks a successful format**: the + media is wiped, the exception replaces the result, and `FormatService.confirm` + never marks the cartridge formatted. +- **`run_campaign.sh` formats six cartridges with no prompt**, and keys on its own + `CAMPAIGN_TAPES` rather than the `OPENBLADE_SCRATCH_BARCODES` the runbook tells + you to narrow (that variable is read only by `tests/hardware/conftest.py`). + `scripts/mhvtl/format-scratch.sh` has a confirmation step; this does not. **On + the real i3, set `CAMPAIGN_TAPES` explicitly and re-read it before running the + format phase.** +- **`_dest_slot`'s error message** renders `min-max` of a slot set that is not + guaranteed contiguous (`SAMPLE_MTX_HIGH_ADDRESSES` has elements at 4096-4099). + The guard itself is a set-membership test and is correct; only the message + could mislead. + +--- + +## 4.

The non-sharded path does this at `archive.py:240`; the sharded path does not. This is what empties the four surfaces above, and it means a second sharded archive onto the same lanes treats them as blank. | +| Spillover, sharded path | `jobs/sharded_archive.py` | No capacity check and no roll-to-next-tape at all. On 95 MiB cartridges the 430 MB dataset failed every batch. A lane filling up is a raw `ENOSPC` in `errors[]`, not a tape change. | +| Catalog namespace, sharded path | `jobs/sharded_archive.py` | Records are keyed on the **absolute source path** (`/srv/…/data/x.bin`), not `/{volume_group}/{relative}` as the non-sharded path does.

No robot, no tape op, no audit record. The tape does not move; the catalog then claims the data left. | +| `TapeOpType.EJECT` | none | Never constructed anywhere, and non-functional if constructed: no library backend defines `eject`, so it silently falls through to an unload into a storage slot. | +| `GET /catalog/seed-demo` | API | Shadowed by `GET /catalog/{file_id}`, declared earlier — always 404s as `file_id="seed-demo"`. | +| `Dockerfile` `OPENBLADE_BACKEND=simulator` | container | Not a valid `BackendMode`; `load_config()` catches the `ValueError` and silently falls back to `mock`. | + +### Does not exist + +| Function | Status | +|---|---| +| **FUSE / NAS mount** | **No FUSE filesystem exists.** No `fusepy`/`pyfuse3`/`llfuse` in `pyproject.toml`; grepping the tree for them returns nothing. `CatalogFilesystem` is a plain 98-line in-process object whose only production consumer is `openblade catalog`. There is no mount command, entrypoint, or unit file. **This is not an environment limitation** — this host has `/dev/fuse` and `fusermount3 3.10.5` available; the feature is simply unimplemented. `docs/fuse.md` says so ("a lightweight namespace abstraction… so future kernel FUSE work can reuse the same contracts"). | +| **Import / export (I/E slot) flows** | No CLI command, no native REST route, nothing in `openblade/hardware/`. `MtxStatus.import_export_slots` is parsed and has **zero consumers**. The AML surface returns 422 for import/export moveClass on i3. The only way to reach an I/E element was the unvalidated `dest_slot_id` of defect 3.9, now closed. | +| **Bulk / directory restore** | `openblade restore` and `POST /restore/` take one catalog path. There is no "restore this volume group" anywhere. The NAS hydration path does bulk work but is pool/dataset-scoped and never populated by the archive jobs. `scripts/campaign/restore_and_verify.py` loops because it has to. | +| **CLI load / unload / move on a real library** | `openblade mock load` / `mock unload` are simulator-only (and now explicitly pinned to `BackendMode.MOCK`). Real media movement is API-only, through `POST /tape-ops/execute`. | +| **CLI sharded archive** | API only. | +| **Drive health / TapeAlert** | No native route. Drive state comes from `/inventory/` and `/status/library`. The rehearsal already recorded that mhvtl does not emulate TapeAlert, so this stays unexercised until the i3. | +| **`WRITE` / `READ` / `VERIFY` tape ops** | No dedicated CLI command or route; reachable only by hand-crafting a `/tape-ops/execute` body. | +| **Virtual namespace over archived data** | `GET /virtual/ls?path=/` returns `{"entries":[],"total_entries":0}` after archiving 450 MB. The NAS namespace is dataset-backed and the archive jobs never create datasets — the two halves of the product are not connected. | + +--- + +## 5. Behaviours worth knowing (not defects) + +- **Symlinks are dereferenced.** A resolvable symlink is archived as a regular + file holding the target's bytes; the link is not preserved. Restoring it + produces a file, not a link. +- **A dangling symlink is silently skipped.** No warning, no error, no entry in + the job result — the job reports `completed` with a file count that is quietly + lower than the source tree. In this campaign: 1,073 archived from 1,074 + entries. +- **Restore to a directory uses the basename only.** `openblade restore --to + /some/dir` writes `/some/dir/{basename}`, so restoring a tree into one + directory collapses same-named files from different subdirectories. Pass an + explicit per-file destination (what the campaign verifier does). +- **`RealLTFSBackend.write_file` reads the whole file into memory** + (`source.read_bytes()`). The 120 MB blob was fully buffered. For a product + targeting multi-TB media this is a scaling limit worth a look. +- **A tape this process has never mounted still assumes 12 GB.** There is nothing + to measure until it is mounted, so `_choose_tape` can pick an over-estimated + tape on the first file after a restart. Left as-is rather than papered over + with a config knob; recorded here instead. +- **Single-file restore load/unloads per file.** 1,073 restores produced ~1,073 + load/unload pairs. 612 s on mhvtl; on a real i3, where a tape change is + measured in tens of seconds, a full restore of this shape is impractical. This + is the strongest argument for a bulk restore path. +- **STRIPE batching is chatty.** One batch of *lane_count* files does + load + mount + write + unmount + unload on every lane. 1,073 files over 3 lanes + produced 358 batches and ~2,166 robot moves. + +--- + +## 6.

Leaving that behind the AML session alone, whose +shipped default credential is `admin`/`password`, is not a defensible place to +draw the line, so it requires the token too. The prefix is a mount point, not a +statement about ownership. + +CORS preflight (`OPTIONS`) is not gated; preflight requests carry no credentials +by definition. + +### Behind a reverse proxy that strips a path prefix + +Tell the **server**, not the request. Start with `uvicorn --root-path /openblade` +(or set `FastAPI(root_path=...)`) so the mount prefix arrives in the ASGI scope, +which is where the router reads it from. + +Do **not** expect `X-Forwarded-Prefix` to do this job for authentication. The +classifier deliberately ignores it: the header is client-controlled, and an +earlier version that honoured it could be tricked into classifying a native path +as an exempt one (`GET /catalog/aml/instances` with `X-Forwarded-Prefix: +/catalog` read as `/aml/instances`), skipping the gate on dozens of routes. An +auth decision must never depend on something the caller can set. + +If you run behind such a proxy *without* configuring `--root-path`, the AML +surface arrives as `//aml/...`, is classified as native, and gets gated. +That fails closed — visibly, and fixed by setting `--root-path`. + +--- + +## What this does not protect + +**The AML emulator surface.** `/aml/*` and `/iblade/*` are a wire-compatible +reimplementation of the Quantum Scalar i3 API, and their authentication is part +of that contract: a `POST /aml/users/login` session, carried as a `sessionID` +cookie or as a bearer token. The native API token neither unlocks nor blocks +them. If you need that surface locked down, that is a separate change to the AML +session layer — do not assume this token covers it. + +**Authorisation.** There is one token and it is all-or-nothing. There are no +scopes, no read-only tokens, no per-user attribution. Anyone holding the token +can format a tape. + +**Transport.** The token travels in a plain header. Terminate TLS in front of +OpenBlade, or keep the port on a trusted network. A bearer token on plaintext +HTTP is a token you have published. + +**Rotation.** Changing the token means editing the env var or file and +restarting. There is no online rotation and no grace period for the old value. + +**The safety gates.** Authentication is orthogonal to +[the safety model](safety-model.md). An authenticated caller still has to do the +dry-run → token → confirm dance to format a tape. + +--- + +## Rolling it out without an outage + +Every client of the native API needs the header before you flip the switch. +In a default deployment that is at least: + +1. **The React frontend**, if it talks to the API from a browser. It has no + place to put a bearer token that a browser user cannot also read — if you + serve the UI publicly, front it with a reverse proxy that injects the header + and authenticates users itself, rather than shipping the token to the client. +2. **Your own scripts and cron jobs.** +3. **Monitoring**, unless it only polls `/health`. + +A safe sequence: + +```bash +# 1. Pick the token, but do not enable it yet. +python3 -c "import secrets; print(secrets.token_hex(24))" | tee /etc/openblade/api-token +chmod 600 /etc/openblade/api-token + +# 2.

Sending the header while auth is still off is a +no-op, which is exactly why it is the right order: you find the client you forgot +*before* it starts failing. + +--- + +## A wrinkle worth knowing: two credentials, one header + +A few native routes — `/api/libraries`, `/status/library`, `/status/catalog`, +`/system/config-summary` — additionally require an **AML session**, because they +read library state through the emulator layer. With native auth enabled, the +`Authorization` header is taken by the API token, so those routes need the AML +session delivered the other way: as the `sessionID` cookie that +`POST /aml/users/login` sets. + +```bash +# Log in for the AML session cookie, then send both credentials. +curl -c /tmp/ob-cookies -X POST http://localhost:8000/aml/users/login \ + -H 'Content-Type: application/json' \ + -d '{"name":"admin","password":"password"}' + +curl -b /tmp/ob-cookies -H "Authorization: Bearer $OPENBLADE_TOKEN" \ + http://localhost:8000/api/libraries +``` + +`require_auth` prefers the cookie and only falls back to the bearer token, so +this works in both modes and is what the i3 compliance suite does. + +--- + +## Troubleshooting + +**Everything returns 401, including with the token.** Check the server actually +loaded the token you think it did. A token file the service user cannot read +fails startup rather than falling back, so look for the startup line first. +Whitespace around the path and around the file's contents is stripped, so that +is not the cause. + +**The browser console shows a CORS error instead of a 401.** Expected. The +rejection happens ahead of the CORS layer, so a cross-origin 401 arrives without +`Access-Control-Allow-Origin` and the browser reports a network failure.

Shard children are that +path plus `#shardNNNN`. + +Verified against the simulator. Remember it when you come to restore: the +group-prefixed path will 404. List the catalog and use what you see there. + +### The number of lanes is what *you* pass + +This is the single most misunderstood part. Shard count is **`len(lane_barcodes)`**. +It is never derived from the file size and never derived from the drive count. +If you pass more lane barcodes than the library has drives, the drive scheduler +rejects the job immediately with `DriveBusyError` — it does not degrade to fewer +lanes. + +`mode: "block_stripe"` with fewer than two lanes is rejected with **422**: + +```json +{"detail": "block_stripe mode requires at least 2 lane_barcodes"} +``` + +Verified against the simulator. + +### `stripe` — whole files across lanes + +- Files are collected with `rglob("*")` and sorted. +- Lane assignment is **positional round-robin over that sorted list**: + `lane = index % lane_count`. Nothing is split; each file is one shard. +- Files are processed in batches of exactly `lane_count`; one batch = one + parallel write round = one atomic commit unit. +- Tape path: `/stripe/`. + +Because assignment is positional, a file's lane **changes** if files are added to +or removed from the source directory. Re-archiving is not lane-stable. + +### `block_stripe` — one file's bytes across lanes + +- The whole-file SHA-256 is computed up front. +- The file is cut into `block_size` blocks (default **128 MiB**) and blocks are + assigned round-robin: `lane = block_index % lane_count`. +- **One shard per lane**, not one per block: each shard is the concatenation of + all blocks belonging to that lane. +- Tape path: `/block_stripe//.shardNNNN`. + +Two operational costs to budget for: + +- Each shard is first written to a **temporary full copy on local disk**, under + `./.openblade-scratch/archive-` — *relative to the process working + directory*. You need roughly 1× the source file in free local space. +- Each of the N workers **re-reads the entire source file** to pick out its own + blocks. Throughput will not approach N× a single drive's rate. + +### Commit is atomic per unit + +The protocol, in order: + +1. Write every shard/file in the unit, and checksum-verify each one. +2. Create catalog rows — instances start as `pending`. +3. Unmount every tape and unload every drive, **aggregating all failures**. +4. Only now flip the instances to `archived`. + +If step 3 fails, the data is on tape but the commit does not happen, and the job +error reads: + +``` +shards written but physical state is unknown (reconcile required): … +``` + +That is deliberate: a dirty unmount or a stuck unload blocks the commit even +though the bytes wrote fine. + +On mid-archive failure, staged instances stay `pending` forever. They are never +selected for restore, so the catalog never claims data it cannot serve — but +there is **no rollback, no erase, no retry and no repair job**. Bytes may sit on +tape unreferenced. + +Commit granularity: `stripe` commits **per batch of `lane_count` files**; +`block_stripe` commits **per file**, and a failure on one file does not stop the +loop. Terminal job state is `completed` if there were no errors, otherwise +`failed_recoverable`. + +### Concurrency caveat + +A `DriveScheduler` is constructed **per HTTP request**, not shared. Archive is +saved by the process-wide archive lock. Restore has no equivalent lock, so +concurrent sharded restores can each believe they own the same drive. +`docs/sharding.md`'s invariant "DriveScheduler never grants the same drive to two +jobs" holds only within one scheduler instance. + +### Checking the result + +``` +GET /catalog/{file_id}/shards # the child records for a sharded file +GET /jobs/{job_id} +``` + +--- + +## 3.

Guessing here unloads the wrong tape; +- a drive whose LTFS volume is still mounted or dirty → refused, for unload **and + for format**. Formatting runs `mkltfs` against a drive, and the orchestrator will + load a slotted cartridge to do it, so a format is also a load — the preview says + which drive it will use, and a mounted volume stops it; +- an archive whose files are already catalogued at those paths → refused. The + catalog write is an upsert, so it would replace the record describing the copy + already on tape; that is a deliberate act for `openblade archive`, not something + to slip through a `y`; +- a restore whose destination **changed** between the preview and your answer → + refused. Whether a restore overwrites is a fact about the filesystem sampled when + the plan ran, and it is what chose the confirmation grade; if a file appeared + while you were reading, the `y` you gave was for a different action; +- a destination slot that is an import/export element → refused.

It runs the **real** dry run — +`FormatService.dry_run`, which mints a one-time `SafetyToken` bound to that barcode +and persists it — and shows you the plan: what is on the cartridge, how much of it, +which pool, the capacity, what the format writes, and how long the token is good +for. Only after you type the barcode does it present that token back to +`FormatService.confirm`, which validates it against the persisted row and deletes +it. There is no branch in which a missing token merely skips a check: no dry run +means no token means the format fails. + +### What tier 1 will not do, even if you say yes + +**Confirmation is not a licence to guess.** If the action cannot name exactly what +it would touch, it is refused and nothing changes: + +- a barcode that isn't in this library → refused, with the barcodes you might have + meant (prefix matches first, then tapes currently in no pool); +- a tape that is already in another pool → refused, naming that pool.

New tools fail **closed**. | +| Read-only proxies | `openblade/assistant/readonly.py` | Read tools see a proxy over the catalog and library whose attribute allowlist contains only read methods. `catalog.create_volume_group` and the library's media moves are not reachable — they raise, they do not return a callable. The proxy keeps no instance state, so `__class__`, `__init__`, `__dict__` and `__reduce__` are refused as well: there is no route back to the live object. | +| Setup allowlist | `openblade/assistant/setup_tools.py` (`SETUP_TOOL_NAMES`) | Exactly two names may ever be tier-1 tools. Anything else raises at registry-build time. | +| Destructive-verb denylist | `openblade/assistant/setup_tools.py` (`DESTRUCTIVE_VERBS`) | A tool name containing any verb of data loss (`format`, `delete`, `erase`, `wipe`, `purge`, `destroy`, `drop`, `truncate`, `clear`, `prune`, `reset`), media movement (`load`, `unload`, `move`, `eject`, `import`, `export`, `mount`), bulk data (`archive`, `restore`, `write`) or trust (`revoke`, `deactivate`, `grant`, `token`, `rename`) is refused **even if someone also adds it to the allowlist**. Widening tier 1 to a destructive action takes two deliberate edits and a test change, not one. | +| Narrow write facade | `openblade/assistant/setup_facade.py` | Tier-1 tools do not get the catalog. They get a facade exposing five named operations; every other attribute — repository methods, `__init__`, `__reduce__`, `_target` — raises. Even the callables it hands back are sealed, because a plain closure or bound method would leak the repository through `__closure__` / `__self__`. The library backend is not behind it at all. | +| Confirmation gate | `openblade/assistant/session.py` | A tier-1 call never runs on arrival. It becomes a `PendingAction` with a preview, and only an explicit `y` executes it. No confirmation callback (one-shot mode) ⇒ the setup tools are not even offered to the model. | +| One write path | `tests/safety/test_assistant_read_only.py` | An AST scan over the whole package: `setup_facade.py` is the only file allowed to name a catalog write method. | +| Media allowlist | `openblade/assistant/media_tools.py` (`MEDIA_TOOL_NAMES`) | Exactly six names may ever be tier-2 tools, and the registry additionally refuses any name already claimed by the tier-1 or read-only registries. The three registries are provably disjoint, so a tool cannot cross a tier boundary by being renamed — and every tier-2 name (`load`, `unload`, `move`, `format`, `archive`, `restore`) is permanently *unregistrable* as a tier-1 tool, because the tier-1 denylist above still rejects all of them. | +| Media facade | `openblade/assistant/media_facade.py` | Tier-2 tools do not get the library backend, the LTFS backend or the repository. They get a facade over thirteen named operations; every other attribute — `library`, `ltfs`, `catalog_repo`, `__init__`, `__reduce__`, `_target` — raises, and the callables it returns are sealed so `__closure__` cannot leak the bundle. Its own validation reads go through the tier-1 read-only proxy. | +| Confirmation grade | `openblade/assistant/media_tools.py` (`ConfirmationGrade`) | The grade is a property of the tool and its resolved plan, never of the model's arguments — a format is always `TYPED`, a restore is `TYPED` exactly when the filesystem says the destination exists. `authorize()` turns what you typed into an authorization; `perform()` **re-verifies** it against the action before calling anything. A forged authorization, one issued for a different action, or a `y` against a typed grade raises and nothing runs — so the strength of the confirmation does not depend on the REPL prompt being written correctly. | +| One media path | `tests/safety/test_assistant_read_only.py` | A second AST scan: `media_facade.py` is the only file allowed to import `openblade.nas` or name `execute_tape_request` / `TapeOpRequest`. `__init__.py` may wire the job services into the bundle and nothing else may name them. | + +All of it is covered by `tests/safety/test_assistant_read_only.py`, and every +structural guard is mutation-checked — remove the guard and a named test fails +(verified, not assumed). The denylist check widens the allowlist on purpose first, +so only the denylist can be what fails it. The source scans walk the whole package +(`rglob`) and assert the exact file list, so a new module cannot quietly fall +outside the guard. + +Every proposed, declined, refused, failed or executed action — both tiers — writes +one structured line to the `openblade.assistant.setup` logger (`actor=assistant tool=… outcome=… args=… +result=…`), JSON-encoded so a crafted name cannot forge a second line. + +It will also **refuse to help you bypass a safety gate**. Ask how to skip the format +safety token and it will explain what that gate protects against and show you the +supported path instead. If you want to exercise a destructive workflow without risk, +the default simulator backend (`OPENBLADE_BACKEND=mock`) already runs the whole +thing against fake hardware. + +## Setup + +### Local Ollama (recommended) + +```bash +# once +curl -fsSL https://ollama.com/install.sh | sh +ollama pull llama3.2 + +# every session (or put it in your shell profile) +export OPENBLADE_OLLAMA_URL=http://localhost:11434 +export OPENBLADE_OLLAMA_MODEL=llama3.2 # optional; this is the default +``` + +Pick a model that supports **tool calling** — the assistant is useless without it. +`llama3.2`, `qwen3`, `mistral-nemo` and `firefunction-v2` all work.

Check the pool before retrying. +- **A read tool hands back live ORM rows.** The proxies stop the assistant's code + from *naming* a write; they do not make writes unreachable in the process, since + a SQLAlchemy row knows its session. That gap is covered by the AST scans over the + package rather than by the proxy, and it predates the two-tier model. +- **Archive and restore block the REPL.** They are synchronous jobs, so the prompt + does not come back until they finish — minutes, on a real library. The lines + before and after are there so a long silence is not mistaken for a hang; do not + reach for Ctrl-C mid-write. +- **The job id arrives after the fact, not before.** `ArchiveService.enqueue` and + `RestoreService.enqueue` create the job inside the same call that runs it, so + the completion line is the first point at which there is an id to print.

Before anything else it does: + +- token not found in the database → `FormatRequiresConfirmationError("Unknown or missing safety token")` +- token found but its `operation` is not `"format"`, or its `target_barcode` is + not the barcode you passed → `FormatRequiresConfirmationError("Safety token does not authorize this barcode")` +- token expired → `SafetyViolationError("Safety token has expired")`, checked one + level down in the domain object + +A token is only ever minted by a dry run, and a dry run refuses a barcode that +is not in live inventory. So a valid token is proof that *a human looked at a +plan naming this specific cartridge, in this library, less than five minutes +ago*. That is the property being protected — not secrecy. The token is printed +in plain text; it is a freshness-and-intent receipt, not a credential. + +**Layer 2 — the orchestrator.** Independently of tokens, +`TapeOperationOrchestrator` refuses any `FORMAT` request whose +`extras["confirmed_format"]` is not literally `True`: + +``` +OperationNotConfirmedError: Format operations require explicit confirmation +``` + +So a caller that reaches the orchestrator directly still cannot format by +accident. + +The net effect of the two layers is that "format" can never be the consequence +of one mistyped command. You have to name the barcode twice, in two separate +invocations, within five minutes. + +--- + +## ⚠️ One endpoint bypasses all of it + +`POST /ltfs/format` formats a tape given only: + +```json +{"barcode": "VOL001L9", "confirm": true} +``` + +No dry run. No token. No `X-Openblade-Service-Token` header. No authentication. +It satisfies layer 2 by setting `confirmed_format` itself, and it never reaches +layer 1 because it calls the orchestrator directly — where `_format()` **mints a +fresh `SafetyToken` for itself** when the caller did not supply one. + +This was confirmed empirically against the simulator: the call returns +`{"status": "completed"}` and the tape is formatted. + +Operator guidance: + +- Treat `/ltfs/format` as a destructive, unauthenticated endpoint.

The two backends + +OpenBlade has one control plane and two backends behind it. + +| | Simulator (`mock`) | Real (`real`) | +|---|---|---| +| Selected by | nothing — it is the default | `OPENBLADE_BACKEND=real` **and** `OPENBLADE_REAL_HARDWARE_ENABLED=true` | +| Moves media | in a Python dict | `mtx` against a SCSI medium changer | +| Writes tapes | in memory | `mkltfs` / `ltfs` against `/dev/sgN` | +| Can destroy data | no | **yes** | +| Everything in this wiki works | yes | mostly — each page flags the gaps | + +**Both variables are required.** Setting only `OPENBLADE_BACKEND=real` leaves +you on the simulator. This is deliberate: the gate is checked in +`require_real_hardware()` (`openblade/hardware/safety.py`), which raises +`RealHardwareDisabledError` unless both hold, and every low-level `mtx`, `sg` +and LTFS wrapper takes the resulting guard object as a required argument. You +cannot reach real hardware without constructing that guard, and you cannot +construct it without both variables. + +`OPENBLADE_REAL_HARDWARE_ENABLED` is compared against the literal string +`"true"`. `1`, `yes` and `TRUE` do **not** enable it. + +--- + +## 2. Install + +```bash +uv venv --python 3.12 .venv +uv pip install -e ".[dev]" +``` + +Python 3.12 is the target — CI, mypy and every Dockerfile assume it, and +`.python-version` pins it. Do not run OpenBlade on 3.10/3.11. + +This puts the `openblade` console script on your PATH. Check it: + +```bash +openblade --help +``` + +--- + +## 3. The simulator round trip + +Every command below was run against the simulator backend while writing this +page. Output is real, lightly trimmed. + +### 3.1 Create a library + +```bash +openblade mock init --slots 8 --drives 2 --cartridges 4 +``` + +``` +Initialized mock library with 8 slots, 2 drives, 4 cartridges +``` + +This **deletes and recreates** the catalog database and overwrites the mock +library state file, both under `~/.openblade/`. Running it again later discards +everything you have archived in the simulator. + +The cartridges are barcoded `MCK00001`…`MCK0000N`. + +### 3.2 Look at it + +```bash +openblade inventory +``` + +``` + Slots +┏━━━━━━┳━━━━━━━━━━┳━━━━━━━━━━┓ +┃ Slot ┃ Occupied ┃ Barcode ┃ +┡━━━━━━╇━━━━━━━━━━╇━━━━━━━━━━┩ +│ 1 │ True │ MCK00001 │ +│ 2 │ True │ MCK00002 │ +│ 3 │ True │ MCK00003 │ +│ 4 │ True │ MCK00004 │ +│ 5 │ False │ │ +... + Drives +┏━━━━━━━┳━━━━━━━━┳━━━━━━━━━┳━━━━━━━━━━━━━┳━━━━━━━━━━━━━┓ +┃ Drive ┃ Loaded ┃ Barcode ┃ Drive State ┃ Mount State ┃ +┡━━━━━━━╇━━━━━━━━╇━━━━━━━━━╇━━━━━━━━━━━━━╇━━━━━━━━━━━━━┩ +│ 0 │ False │ │ empty │ unmounted │ +│ 1 │ False │ │ empty │ unmounted │ +└───────┴────────┴─────────┴─────────────┴─────────────┘ +``` + +Slots are 1-based. Drives are **0-based** — that asymmetry is real and it bites +people. See [drives & changer ops](drives-and-changer.md). + +### 3.3 Format a tape + +Formatting is two-step and refuses without a token. Full explanation in +[formatting tapes](formatting-tapes.md); the short version: + +```bash +openblade format dry-run --barcode MCK00001 +``` + +```json +{ + "operation": "format", + "target": "MCK00001", + "affected_barcodes": ["MCK00001"], + "warnings": ["Destructive operation", "Inventory barcode must match confirmation"], + "is_destructive": true, + "token": "pQwmEs2ZlP05V4eYhX1JcgJK9gSoTGmpyso0t7ji7YI" +} +``` + +```bash +openblade format confirm --barcode MCK00001 --token pQwmEs2ZlP05V4eYhX1JcgJK9gSoTGmpyso0t7ji7YI +``` + +```json +{"success": true, "message": "formatted", "details": {"barcode": "MCK00001", "formatted": true}} +``` + +The token expires after **5 minutes** and is **single-use** — running the same +`confirm` twice fails the second time. Verified. + +### 3.4 Create a volume group and archive into it + +```bash +openblade volume-group demo-vg +openblade archive --volume-group demo-vg --path /some/source/dir +``` + +```json +{"job_id": "d0398cd5-9bae-4c5b-b7f3-8543b5ba7bd3", "status": "completed", "job_type": "archive"} +``` + +> **The CLI blocks until the archive finishes.** The help text says "Enqueue an +> archive job", but `ArchiveService.enqueue()` calls `run_archive_job()` inline. +> There is no background worker. The HTTP API is the same underneath, but it +> *reports* `202 Accepted` / `"pending"`, which is misleading — see +> [jobs & monitoring](jobs-and-monitoring.md). + +### 3.5 Browse the catalog + +```bash +openblade catalog / +openblade catalog /demo-vg +``` + +``` + Catalog /demo-vg +┏━━━━━━━━━━┳━━━━━━┳━━━━━━┳━━━━━━━━━━━━━━━━━━━┓ +┃ Name ┃ Type ┃ Size ┃ Path ┃ +┡━━━━━━━━━━╇━━━━━━╇━━━━━━╇━━━━━━━━━━━━━━━━━━━┩ +│ note.txt │ file │ 16 │ /demo-vg/note.txt │ +└──────────┴──────┴──────┴───────────────────┘ +``` + +Note the catalog path: **the volume group name is the first path segment**, and +the source directory's own name is not in it. `/src/note.txt` archived into +`demo-vg` becomes `/demo-vg/note.txt`. + +### 3.6 Restore and check the bytes + +```bash +openblade restore --path /demo-vg/note.txt --to /tmp/out/note.txt +cat /tmp/out/note.txt +``` + +``` +hello openblade +``` + +Restore verifies the SHA-256 before handing you the file. See +[restoring](restoring.md). + +### 3.7 Check the job log + +```bash +openblade jobs +openblade jobs d0398cd5-9bae-4c5b-b7f3-8543b5ba7bd3 +``` + +That is the whole round trip. If all seven steps worked, your install is good. + +--- + +## 4. The HTTP API + +The CLI covers a deliberately small slice. Sharded archive, tape operations, +the NAS surfaces and everything the web UI uses are **API-only**. + +```bash +uvicorn openblade.api.main:app --reload +``` + +Then `http://localhost:8000/docs`. Unauthenticated health probes: + +```bash +curl localhost:8000/healthz # component health: database, library, ltfs +curl localhost:8000/readyz # ready only if database AND library are OK +curl localhost:8000/version +``` + +Full route list: [API reference](../reference/api.md) (generated). + +> `/health` and `/healthz` are **different endpoints**. `/health` returns +> `{"status":"ok","backend":"mock"}` and checks nothing. +> `docker-compose.yml` health-checks `/health`, so a container with an +> unreachable database still reports healthy. Probe `/readyz` instead. + +--- + +## 5. ⚠️ The CLI is simulator-only + +**Almost every `openblade` command runs against the simulator no matter what +`OPENBLADE_BACKEND` says.** Only two commands read the real configuration: + +- `openblade hardware connect-i3` +- `openblade hardware validate-ltfs` + +Everything else — `inventory`, `archive`, `restore`, `jobs`, `catalog`, +`format dry-run`, `format confirm`, `volume-group`, and all of `mock` — goes +through `_get_context()`, which builds its config by hand in +`openblade/cli/main.py:_default_config()`. That helper never calls +`load_config()`, so the backend stays at its `mock` default and +`OPENBLADE_DB_URL` is ignored. + +Verified: with `OPENBLADE_BACKEND=real OPENBLADE_REAL_HARDWARE_ENABLED=true` and +a deliberately nonexistent `OPENBLADE_DB_URL`, `openblade inventory` **exits 0 +and prints the simulator's cartridges**. No error, no warning. + +Two ways this hurts: + +1. **It looks like a successful hardware check and is not.** A plausible list of + tapes appears, and they are not your tapes. +2. **`openblade format confirm` reports `"formatted": true` without touching a + physical cartridge.** See [formatting tapes](formatting-tapes.md). + +**Drive real hardware through the HTTP API**, started with the real-hardware +environment set. Use the CLI for the simulator and for the two `hardware` +validation commands. + +Same root cause, smaller blast radius: running `openblade jobs` against a server +started with `OPENBLADE_DB_URL` set shows you a *different* database, which will +look empty. See [the catalog](the-catalog.md). + +--- + +## 6. Before you point it at real hardware + +Do not set the two environment variables yet. In order: + +1. Complete the simulator round trip above. +2. Read the [safety model](safety-model.md) — in particular which guards are + simulator-only and therefore **do not protect real tapes**. +3. Read [drives & changer ops](drives-and-changer.md) and set + `OPENBLADE_DRIVE_SERIAL_MAP`. With more than one drive, skipping this is how + you write to the wrong drive. +4. Work through [hardware bring-up](hardware-bring-up.md), which points at + `docs/runbooks/real-i3-bringup-plan.md` — the ordered obstacle list. +5. Rehearse against mhvtl first (`scripts/mhvtl/setup.sh`). That virtual-library + pass found six product defects before any real cartridge was at risk; see + `docs/runbooks/mhvtl-rehearsal.md`. + +A dry-run mode sits between simulator and live: with the real backend selected, +`OPENBLADE_HARDWARE_DRY_RUN=true` logs every `mtx`/`ltfs` command line without +executing it.

Two different failure shapes here: asking for **more shards than the + library has drives** fails immediately with `DriveBusyError`, but if the + drives merely happen to be *busy*, the request **blocks for the 300-second + default timeout** before raising the same error. A five-minute stall is that + timeout, not a deadlock. +5. Read every shard in parallel into a scratch directory. +6.

The mount-state unload gate ⚠️ + +The rule — unload only when mount state is `unmounted` and drive state is +`loaded` or `failed` — is enforced in exactly one place: +`MockLibraryBackend.unload()`. + +**`RealLibraryBackend.unload()` has no such check.** It calls the changer +directly and records the new mount state afterwards. `docs/safety.md`, +`README.md` and `docs/architecture.md` all state this guarantee without the +qualification. + +What does protect real tapes is the unmount path, which waits for the LTFS FUSE +process to release the device before reporting success, and treats "I could not +read `/proc`" as "still held". See +[drives & changer ops](drives-and-changer.md). + +**Operator rule:** on real hardware, never script an unload immediately after an +unmount without checking the unmount result's `device_released` field. + +## 4. The drive ownership gate ❌ + +`JobQueue.claim_drive()` is **never called by any production code**. A `JobQueue` +is constructed at startup and handed to the services; none of them use its +ownership methods, and its state never reaches the database. + +What actually serialises drive access: + +- a process-wide lock around **archive** requests (not restores), +- the orchestrator's per-drive lock for write and format, and per-barcode lock + for read and verify, +- `DriveScheduler` for sharded jobs — real, but constructed **per HTTP request**, + so two concurrent requests hold independent lock tables. + +## 5. The changer ownership gate ⚠️ + +`JobQueue.claim_changer()` is likewise never called. The simulator does serialise +the changer with a non-blocking lock (`ChangerBusyError: Changer is already +moving media`). The real backend has no equivalent; it trusts `mtx`. + +Load, unload, move and eject take **no orchestrator lock at all**. + +## 6. The archive completion gate ⚠️ + +The **sharded** engine genuinely implements it: every shard is checksum-verified, +then every tape is cleanly unmounted and unloaded with all failures aggregated, +and only then are catalog instances flipped from `pending` to `archived`. A dirty +unmount blocks the commit even though the bytes wrote fine, with the error +`shards written but physical state is unknown (reconcile required)`. + +The **classic** engine is weaker: it writes catalog rows per file and, on +failure, deletes rows for files that never reached tape. The doc's phrasing +overstates its atomicity. + +## 7. Source retention ✅ + +No code path deletes an archive source. Deletion is always the operator's +separate act. + +## 8. "Read-only default for hardware" ❌ as written + +There is no read-only hardware mode flag. The default is `mock` — i.e. no +hardware at all. The effect is safe; the description is not accurate. + +--- + +## Not a gate, but it decides who can reach the gates: API authentication ⚠️ + +None of the eight gates above asks *who is calling*. Gates 2–6 constrain what a +caller may do; they assume the caller is entitled to be there at all. That +assumption is only true if the port is. + +The native REST API ships with **authentication off by default**, which means +every operation the gates permit — enqueue an archive, mount, unload, format with +a freshly-minted token, run the test runner — is available to anyone who can open +a socket. This is fine on a loopback-only port and unacceptable on anything else. + +Set `OPENBLADE_API_TOKEN` or `OPENBLADE_API_TOKEN_FILE` and every native route +requires `Authorization: Bearer `, enforced in one middleware ahead of +routing so there is no per-route list to get wrong. `/health`, `/healthz` and +`/readyz` stay open for monitors; the `/aml/*` and `/iblade/*` emulator surface +keeps its own separate session login and is unaffected either way. + +It is a coarse instrument: one token, no scopes, no read-only mode, no per-user +attribution. Holding the token means holding every gate's key. Full detail, +including the file-based form and a rollout order that does not break your +clients, is in [API authentication](api-authentication.md). + +When auth is disabled the server logs a `!!!

Expect to meet it for the first time at the library. + +### Kernel module taints on `modprobe mhvtl` + +``` +mhvtl: loading out-of-tree module taints kernel. +mhvtl: module verification failed: signature and/or required key missing +``` + +Both messages are **expected and harmless** for an unsigned out-of-tree module. +They are *fatal* under Secure Boot — check `mokutil --sb-state` first. + +### `modprobe` fails, or the build does + +You need `linux-headers-$(uname -r)` for the **running** kernel, root, and a real +host (not an unprivileged container). + +--- + +## Device nodes + +### `LTFS11253E No index found in the medium` on a tape you know is good + +``` +LTFS17016E Cannot parse index direct from medium (-21700). +LTFS11253E No index found in the medium. +LTFS11027E Cannot mount volume: medium consistency check failed. +``` + +**This is a wrong-device-node error masquerading as bad media.** It is the single +most misleading failure in the system, and it is exactly how an operator ends up +throwing away a healthy cartridge. + +The LTFS `sg` backend addresses drives as `/dev/sgN`. If it is handed `/dev/stN` +it does not error cleanly — it reads the wrong device and reports the above. + +Fix: OpenBlade resolves the mapping via `resolve_sg_device()`, reading +`/sys/class/scsi_tape//device/scsi_generic/`. If you see this anyway: + +- Check what you put in `OPENBLADE_DRIVE_DEVICES`. Use **no-rewind `nst`** nodes. +- **Never derive the `sg` number from the `st` number.** They are allocated + independently; `st0 -> sg1` and `st2 -> sg4` are routine. +- Remember that the discovery fallback returns the *rewinding* `stN` node + ([drives & changer ops](drives-and-changer.md)), so set the variable explicitly. + +### `sg_inq` exits 50 — "close error: No medium found" + +The inquiry itself **succeeded**; only the close failed.

If the header says 12 and you count 8, the four mailslots are the +difference. + +If they are genuinely missing — a tape in the mailslot is invisible — that was a +real parser bug (`Storage Element 9 IMPORT/EXPORT:Empty` did not match the slot +regex). It is fixed; if you see it again, capture `mtx -f status` +verbatim and file it. + +### A tape is visibly in a drive but `Barcode X not found in inventory` + +Historically this was a parser bug: `mtx` is inconsistent about whitespace around +`=`, + +``` +Data Transfer Element 0:Full (Storage Element 6 Loaded):VolumeTag = OB0007L8 + Storage Element 1:Full :VolumeTag=OB0001L8 +``` + +and the barcode regex required the tight form, so **every tape loaded in a drive +parsed as `barcode=None`**. Fixed. + +If you see it now, the likelier cause is that `NoScratchMediaError` is being +raised for a *different* reason — the same exception class carries three +different messages: + +| Message | Real cause | +|---|---| +| `No scratch media with sufficient capacity is available` | genuinely no tape with room | +| `Barcode X not found in inventory` | selection/inventory mismatch | +| `No available drives for archive load` | **every drive is busy** | + +All three surface as HTTP **503**. Read the detail string. + +--- + +## Mount and unmount + +### `LTFS30210I Cannot open device: failed to open /dev/sg2 (16)` on a remount + +`16` is `EBUSY`. `umount` returns as soon as the kernel detaches the filesystem, +but the LTFS FUSE process lives on to flush its index and close the drive. Until +it exits, the drive's `sg` node is held. + +OpenBlade now polls `/proc` and waits for release, reporting `device_released` in +the unmount result. Any unmount→remount cycle hits this without the wait, and on +a real library so does unload→reload. + +If you script around OpenBlade: **check `device_released` before unloading.** + +### `TapeMountedError: Drive 0 cannot be unloaded while mounted_rw` + +Working as intended — unmount first.

If a doc +tells you a volume group has a `shard_width` or a list of `lanes`, it is +describing a design that was never built. + +A cartridge's `volume_group_id` is nullable — a tape with no group is +"unassigned", which is a normal and expected state. + +A file record's `volume_group_id` is **not** nullable.

See +> [restoring](restoring.md). + +--- + +## "Pool" is a different thing — three of them, in fact + +Do not treat "pool" as a synonym for volume group. + +1. **`NasPool`** — a NAS-layer object with a `volume_group_ids` field. The + hierarchy is *pool → list of volume-group ids → cartridges*. That field is a + **JSON list of strings, not a foreign key**: nothing checks that the groups + exist, and deleting a group does not update any pool. + CRUD at `/nas/pools` (and `/storage/nas/pools` — the router is mounted twice). +2. **AML media pools** — `default`, `cleaning`, `pool-critical`, `pool-general`, + `pool-cold`, seeded inside the Quantum emulator state.

It is a two-phase +first-fit: + +**Phase 1 — tapes already in the group.** List the group's cartridges, excluding +any in state `exported`, skip `CLN*` cleaning tapes, and return the **first** one +with `remaining_capacity >= file_size`. + +**Phase 2 — recruit an unassigned tape.** If nothing in the group fits, walk +every barcode visible in the library (slots + drives), skip `CLN*`, skip tapes +belonging to a *different* group, skip `exported`, skip ones too small — and the +first survivor is **assigned to this volume group** and used. + +Side effect worth knowing: phase 2 calls `add_cartridge()` — which inserts **and +commits** — for *every* inventory barcode it examines, including the ones it then +rejects. So a single archive can create catalog rows for tapes it never used. +Same phantom-row class as the unvalidated assign endpoint +([inventory & barcodes](inventory-and-barcodes.md)), but here the archive engine +is the source. + +Failure: `NoScratchMediaError`, HTTP **503**. + +### Consequences you need to know + +- **Ordering is ascending barcode string order, not free space.** Both phases + iterate `ORDER BY barcode`. `AAAA0001` is filled completely before `AAAA0002` + is touched.

Phase 2 claimed it. +- **A typo in the group name creates a new group.** `run_archive_job` creates the + group if it does not exist.

(The +forbidden call patterns are described here rather than written out, because the +guard is a line-based substring scan and spelling them would trip it — the same +reason :mod:`openblade.assistant.readonly` describes its one indirectly.) + +Ambiguity refuses even when confirmed. Every operation has a ``plan_*`` twin that +resolves the target against the live library before the operator is asked, and the +executing operation resolves it *again* inside the write path. An unknown barcode, +a barcode that somehow appears in two places, an occupied target drive or slot, or +a drive with LTFS still mounted stops the action with +:class:`~openblade.assistant.errors.MediaRefusedError` and the candidates the +operator plausibly meant — before any prompt is printed. +""" + +from __future__ import annotations + +import time +from collections.abc import Callable, Sequence +from dataclasses import dataclass +from pathlib import Path, PurePosixPath +from typing import Any + +from openblade.assistant.errors import ( + MediaFacadeViolationError, + MediaOperationFailedError, + MediaRefusedError, +) +from openblade.assistant.readonly import AllowlistProxy, ReadOnlyProxy +from openblade.domain.errors import OpenBladeError, safe_job_error +from openblade.nas.tape_orchestrator import TapeOperationFailedError, execute_tape_request +from openblade.nas.types import TapeOpRequest, TapeOpType + +JSONDict = dict[str, Any] + +# Mount states in which a drive is holding a volume.

The same + no-instance-state machinery backs both write facades: the tier-1 one allowlists + two catalog-only setup operations, the tier-2 one thirteen named media + operations, and neither exposes the object it wraps under any name at all. +2. :mod:`openblade.assistant.tools` — the tool registry refuses to build unless + every registered name is on ``READ_ONLY_TOOL_NAMES``.

It does not + account for the index that will be written when we unmount. +* Free space does not arrive one byte at a time. ``used_bytes`` for a tape this + process has not mounted comes from the catalog and is byte-granular, so a + free figure of "512 bytes" is entirely representable there and is exactly the + state nothing can be written into. + +Measured on the mhvtl rig (2026-09-11, one 8000 MB cartridge formatted, filled +with incompressible data until ``write`` returned ENOSPC): + +* capacity 6,569,328,640 bytes, ``f_frsize`` 524,288 -- LTFS reports free space + in 512 KiB blocks, so on that path ``f_bavail`` steps 524,288 -> 0 and the + sub-block tail of the medium is never visible as free space at all. +* at ``free == 0``, creating a **zero-byte file** fails with ``ENOSPC`` -- + the campaign's failure, reproduced directly. +* unmounting that 100%-full tape succeeded, so on this rig the drive's own + end-of-medium margin absorbed the final index write. + +In other words the rig can demonstrate the zero-free half of the problem but +not the nonzero-free half, because its free-space reporting cannot express it. +The reserve is therefore sized conservatively rather than fitted to a measured +failure point: it costs 0.001% of a real LTO-8 cartridge, and the failure it +prevents cost the campaign an aborted 1,073-file archive job. + +So the reserve is **the smaller of 64 MiB and 1% of the medium's capacity**: + +* 64 MiB is the ceiling, and comfortably covers a full-cartridge index plus + block-size rounding on real LTO media.

The +host numbers tape devices ``/dev/nst0..nstN-1``. **Nothing guarantees the two +orders agree.** With one drive the mistake is invisible; with two or three it is +the classic "wrote to the wrong drive" bug — the changer loads a cartridge into +DTE 1 and the writer streams LTFS into whatever cartridge happens to be in +``/dev/nst1``. See ``docs/runbooks/real-i3-bringup-plan.md`` (Phase 2). + +The design chosen (and why) +--------------------------- +The authoritative SCSI route is READ ELEMENT STATUS with the DVCID bit, which +returns each element's device identifier; the library then tells you which serial +sits in which element. ``mtx status`` does **not** print serials, and no tool in +this repo issues READ ELEMENT STATUS — wiring it up means a new binary dependency +(``sg_read_element_status``/``sg_ses``) plus a hex descriptor parser we could not +validate against any captured real-i3 output. Shipping an unvalidated binary +parser on the write path is worse than shipping no correlation. + +So correlation here is **operator-declared, with a machine-checked serial set**: + +1. ``OPENBLADE_DRIVE_SERIAL_MAP=":,..."`` — the operator reads each + drive's serial off the i3 web UI (which shows serial *per drive bay/element*) + and declares the mapping once. **The element index is 0-based** (``mtx``'s + Data Transfer Element numbering); the i3 UI numbers drive bays from 1. +2. At startup every configured device is probed with ``sg_inq`` and its live + *Unit serial number* is compared against the declaration.

Confirmation is not a licence to guess. +3. With no map declared, correlation falls back to **positional** order and logs + a loud warning that the ordering is UNVERIFIED. This preserves today's + behaviour (a single-drive library is unaffected) while making the ≥2-drive + risk visible in the log instead of silent. + +**The limit of the check, stated plainly.** Nothing in this design ever observes +which serial is in which element, so the serial check proves the *set* of +attached drives is the set that was declared — it CANNOT detect a declaration +whose elements are transposed or rotated (e.g. an operator who read 1-based bay +numbers off the UI). ``serials_verified`` says exactly that and nothing more; no +log line or report field claims the element assignment itself was verified. +Proving that requires either READ ELEMENT STATUS with DVCID, or an empirical +check (load a scratch tape into element *k* and confirm only the correlated +device reports a tape online) — both are follow-on work for the bring-up, and +``docs/hardware-setup.md`` tells the operator to do the empirical check by hand. + +The serials are captured either way, so ``connect-i3`` output tells an operator +exactly what to paste into ``OPENBLADE_DRIVE_SERIAL_MAP``. + +A backend that can *ask the library* which drives it has (the AML Web Services +backend can; ``mtx`` cannot) gets one more check on top of the two above: +:func:`verify_against_library_serials` compares the declared serials with the +serials the library reports, which catches a declaration that matches this +host's drives but belongs to a different library.

Unloading + then can discard an index that was about to be written — and a failed test + run, which is when you reach for `reset.sh`, is exactly when a mount has been + left behind. +- **Positive barcode confirmation before any format.** Barcodes must be + well-formed, are matched against the *whole* VolumeTag (a substring match + would let `OB000` select a data tape), and after loading, the drive is + re-read — the cartridge actually in the drive must carry the requested + barcode before `mkltfs` runs. `mkltfs` formats whatever it finds; it does not + check barcodes. + +## The configuration + +`config/` is installed verbatim into `/etc/mhvtl`. + +| File | Contents | +|---|---| +| `device.conf` | Library 10 (`QUANTUM` / `QUANTUM Scalar`) + drives 11/12/13 (`IBM ULT3580-TD8`, serials `OBLADE_D01..03`). | +| `library_contents.10` | 3 drives, 1 picker, 4 MAP (I/E) slots, 8 storage slots. | +| `mhvtl.conf` | `CAPACITY=8000` (MB). mhvtl's 500 MB default is too small for the 100 MB payloads the suite writes. | + +### Media + +| Barcode | Slot | Role | +|---|---|---| +| `OB0001L8` – `OB0004L8` | 1–4 | data media | +| `CLN001L8` | 5 | cleaning cartridge (exercises the `CLN` branch in the parsers) | +| `OB0007L8`, `OB0008L8` | 6–7 | **scratch** — the only barcodes destructive tests may format | +| — | 8 | deliberately empty, so inventory has an unoccupied slot | + +## Why the library is called "QUANTUM Scalar" + +mhvtl picks its medium-changer personality in +`usr/cmd/vtllibrary.c:customise_lu()` by matching the **product id** (not the +vendor id) against `QUANTUM` / `ADIC`. A product id of `Scalar i3` — what a real +i3 actually reports — falls through to the *default* personality, which uses +completely different SCSI element addresses: + +| personality | `start_drive` | `start_map` | `start_storage` | +|---|---|---|---| +| `scalar_pm` | `0x0100` (256) | `0x0010` | `0x1000` (4096) | +| `default_smc_pm` | `0x0001` | `0x0300` | `0x0400` (1024) | + +We deliberately take the Scalar numbers: rehearsing against them proves the +backend never assumes slots are 0- or 1-based, which is the element-addressing +trap Phase 2 of the bring-up plan asks this rig to exercise. + +(`mtx` presents 1-based logical element numbers regardless, so OpenBlade sees +slots 1–12. The raw addresses matter to anything issuing SCSI directly.) + +## Three upstream obstacles this rig works around + +All three are mhvtl bugs, not OpenBlade bugs. Each is documented at the point it +bites; summarised here so you recognise the symptom on a new host. + +**1. `vtllibrary` aborts with heap corruption under the Scalar personality.** +`malloc(): invalid next size (unsorted)`, immediately after +`smc_personality_module_register(): mhVTL - Scalar emulation`. `scalar_pm.c` has +two `snprintf` bounds that exceed their `alloc_vpd()` page (VPD `0x80` writes 25 +bytes into 24; VPD `0x83` writes 25 bytes at offset 12 of a 36-byte page), and +both functions free the old page **without storing the new one back into +`lu->lu_vpd[]`**, leaving a dangling pointer. Fixed by +`patches/0001-scalar_pm-fix-vpd-overflow-and-uaf.patch`, which `setup.sh` +applies. + +**2. mhvtl's own systemd units stop its daemons from working.** Two independent +problems in `vtltape@.service` / `vtllibrary@.service`: + +- `ProtectClock=yes` implies a `DeviceAllow=` rule, and setting *any* + `DeviceAllow` switches the cgroup device policy from `auto` to **closed** — + which then denies the daemon its own `/dev/mhvtl` node. Symptom: + `chrdev_create(): Error creating device node for mhvtl: Operation not + permitted`, or `Could not open transport for minor NN: Operation not + permitted`. +- `ProtectKernelTunables=yes` mounts `/sys` read-only, so the daemon cannot + write `/sys/bus/mhvtl/drivers/mhvtl/add_lu` to register its logical unit. + Symptom — the nasty one — the daemon reports **`active`** while **no SCSI + device ever appears**: `Could not open 'add_lu': Read-only file system`. + +`setup.sh` writes drop-ins under `/run/systemd/system/` (so they vanish on +reboot and never edit a packaged unit) re-allowing the module's dynamic +character major and turning `ProtectKernelTunables` off. + +**3. `lsscsi` prints the `mediumx` row before udev creates its `/dev/sg` node.** +A readiness check that waits only for the row sees a changer whose sg column is +`-`, and `mtx -f -` then fails. `setup.sh` waits for the sg nodes themselves. + +## Three traps this rig is specifically here to expose + +**Drive order is not device order.** mhvtl hands out `/dev/stN` in daemon +*registration* order, which does not track SCSI target order. Across reboots of +this rig we have seen targets 1/2/3 map to `st0/st1/st2` **and** to `st2/st1/st0`. +`setup.sh` prints the SCSI-address → `/dev/st` → serial correlation on every run +rather than letting anyone assume it. Correlate drives by **serial number**, never +by device numbering — the same instruction Phase 3 gives for the real i3. + +**`/dev/sg`, `/dev/st` and `/dev/nst` are not interchangeable.** + +- LTFS's `sg` backend addresses drives as `/dev/sgN`. Given `/dev/st0` it reads + the wrong device and reports `No index found in the medium` — a wrong-device + error that looks exactly like blank media. +- `sg_inq` against the **rewinding** `/dev/stN` exits 50 (`close error: No medium + found`) whenever the drive is empty, because closing a rewinding node attempts + a rewind. The inquiry succeeds; the command still reports failure. +- `stN` and `sgN` numbers are allocated independently. `st0 -> sg1` and + `st2 -> sg4` are both real pairings from this rig. Never derive one from the + other; `openblade.hardware.discovery.resolve_sg_device()` reads the mapping + from sysfs. + +**An import/export slot is not a storage slot.** The rig ships 8 storage slots +plus 4 I/E (mailslot) elements, which `mtx` reports as slots 9–12 with an +` IMPORT/EXPORT` infix. They are easy to parse into the same list as storage +slots and that is a data-loss shape: on a full library the first *empty* +element is the mailslot, so "unload to the first free slot" ejects the +cartridge to the operator front panel. `openblade.hardware.mtx` keeps them in +`MtxStatus.import_export_slots`, separate from `MtxStatus.slots`. Leave slot 8 +empty in any config you derive from this one, so the storage-slot path is +always exercised with somewhere to unload to. + +## Requirements + +- Linux with headers for the **running** kernel (`linux-headers-$(uname -r)`). +- Secure Boot **disabled**, or the unsigned out-of-tree module will not load. +- Root. Not usable from inside an unprivileged container — the module must be + loaded on the host. +- `lsscsi`, `sg3-utils`, `mtx`, `zlib1g-dev`, `liblzo2-dev`, `build-essential` + (installed by `setup.sh` unless `SKIP_APT=1`). +- LTFS is **optional but strongly recommended**. Without `mkltfs`/`ltfs` the + discovery, drive-health and changer suites still run; the LTFS, + archive/restore, sharded and performance suites do not. See the runbook for + the build recipe — there is no Ubuntu package. + +`setup.sh` env overrides: `MHVTL_SRC` (default `/usr/local/src/mhvtl`), +`MHVTL_REF` (default: the pinned commit `59f32ee5`), `SKIP_APT=1`. + +The ref is pinned, not floating: `patches/` is byte-exact against that commit +and the results in the runbook are from that build. Bump it deliberately and +re-run the suite — a moving `master` gives the next person either a hard +"failed to apply" or, worse, a quietly different rig. diff --git a/scripts/mhvtl/_rig.sh b/scripts/mhvtl/_rig.sh new file mode 100755 index 0000000..5fd4fe9 --- /dev/null +++ b/scripts/mhvtl/_rig.sh @@ -0,0 +1,161 @@ +#!/usr/bin/env bash +# shellcheck shell=bash +# +# Shared helpers for the mhvtl rehearsal rig scripts.

Both functions dealloc_vpd() the existing page and assign the replacement + to a LOCAL variable, never storing it back into lu->lu_vpd[PCODE_OFFSET(x)]. + The logical unit is left holding a dangling pointer to freed memory, and + the new page leaks. Compare init_default_smc(), which assigns through. + +The fix renders each field into a scratch buffer that is always large enough, +memcpy's exactly the page payload, and installs the new page before anything +can observe the stale pointer. + +CAVEAT, unchanged from upstream: VPD page 0x80 is 24 bytes but its content is +vendor id + "%-17s" serial. With an 8-character vendor id that is 25 +characters, so the last byte is dropped. This patch makes the truncation +explicit and safe rather than a buffer overrun; it does not enlarge the page, +because the page size is what the Quantum SCSI reference specifies.
