Unreleased

2.1.0 - 2026-02-05

Changes

  • Add configurable resource timeout for all operations. (31276c2)
  • Add CORS configuration for the gateway server. (722d7e6)

2.0.0 - 2025-12-04

Breaking Changes

  • Change the default HTTP port from 8080 to 8337. (6ace6105)

1.9.0 - 2025-07-08

Changes

  • Add a Server header to the REST API responses to identify the LINSTOR Gateway server. (82c9a4fe)
  • Generate Software Bill of Materials (SBOM) files for each release. (173ab210)
  • Clarify a health check message about the targetcli package. (df6af21c)

Fixes

  • Make the first 8 bytes of the product_id unique so that VMware ESXi does not consider two devices to be identical. (f9510879)

1.8.0 - 2025-03-18

Changes

  • Add a health check for the fuser tool (20f28d80)
  • Disallow uppercase characters when creating iSCSI IQN (9754bf6d)

1.7.0 - 2024-11-26

Changes

  • Change the scsi_sn and product_id calculations so that they are both unique per volume. (0d144af9)

1.6.0 - 2024-07-18

Fixes

  • Correct a statement about multiple exports in the "nfs create" help text. (ba82ed58)

1.6.0-rc.1 - 2024-07-04

Changes

  • Add a sensible User-Agent when sending http requests via the client. (fc34f086)
  • NFS: Let LINSTOR set the file system owner of the export's root directory. This allows XFS file systems to be used with NFS exports. (01161bfc)
  • NFS: Add a --filesystem option when creating an NFS export. (86b70a58)

Fixes

  • Fix some Go API client functions so that they actually return data. (34f68fc3)

1.5.0 - 2024-04-17

Features

  • Added hints to some health check outputs to help users resolve potential issues. (09e0860)
  • New health check for NVMe-oF resource agents. (d3441f5)
  • New health check for SCST kernel modules and user space utilities. (138c1f6)
  • The drbd-reactor health check now also checks that if the drbd-reactor-reload.{path,service} files are up-to-date. (2c40ff0)
  • When creating a resource, linstor-gateway now waits a few seconds to ensure that the resource is actually running. This prevents situations where the resource fails to start, but linstor-gateway still reports it as "running". (2c40ff0)
  • Various improvements to the end-to-end tests.

1.4.0 - 2024-03-04

  • No changes over rc1

1.4.0-rc.1 - 2024-02-20

Features

  • The nfs create command now supports creating multiple NFS exports in the same cluster. (6244defb)
  • The delete command now prompts for confirmation before deleting a resource. (7c6d7833)
  • drbd-reactor configuration files generated by LINSTOR Gateway are now versioned and can be migrated to new versions automatically. (87230226, f72c2c39)

Fixes

  • The nfs upgrade command now actually respects the --dry-run flag. (e760b419)
  • drbd-reactor configuration files no longer include the deprecated id field. (878d53f4)
  • In the NFS configuration file, the IPaddr2 and nfsserver resource agent entries were switched. These are now in the correct order. (2337e327)

1.3.0 - 2023-10-24

  • No changes over rc1

1.3.0-rc.1 - 2023-10-16

Features

  • The status command will now show what node a resource is running on. (106dfc88)
  • The check-health command now differentiates between "agent", "server", and "client" mode, checking the requirements for the respective mode of operation. (e0b25072)
  • All create commands now use -r as the shorthand flag for resource groups. Previously, iSCSI used -g instead -- this shorthand is now deprecated. (5b0eb9ab)
  • When creating an iSCSI target, the --implementation flag can now be used to specify what iSCSI target implementation should be used by the underlying resource agent. (e6bcc14f)
  • When a step in the creation of a resource fails, the resources created in previous steps will now be cleaned up. This avoids "resource already exists" errors. (434d2d13)
  • When installing LINSTOR Gateway via rpm, the drbd-reactor auto-reload files will now be copied to the appropriate place automatically. (736cd2ae)

Fixes

  • The check-health command now finds the correct path to the drbd-reactor documentation directory more reliably. (bc4747ac)

1.2.0 - 2023-03-14

Features

  • When creating a resource (iSCSI, NVMe-oF, or NFS), LINSTOR Gateway will now do a basic check for IP collisions. If the provided service IP is already in use by another resource, an error will be thrown. (48ac8502)

Fixes

  • The CLI will no longer print the usage information whenever an error happens. (4e2cc19c)
  • When listing resources, degraded resources could previously be displayed twice. This was changed so that every resource only gets reported once. (a4b56ceb)
  • Remove a check that verifies a resource is stopped before adding a volume. Adding volumes works just as well on running resources. (8426c36e)

1.1.1 - 2023-03-06

Fixes

  • Fix NFS healthcheck on older systemd versions (53bbd671)
  • Ignore and overwrite an existing promoter config if its corresponding LINSTOR resource does not exist (137f7560)
  • Fix a nil dereference when listing resources with a broken LINSTOR state (df53d0b3)

1.1.0 - 2023-02-24
