NFS kernel modules not included

[bgamari]

The kernel configuration appears not to set CONFIG_NFS, precluding use as an NFS client.

Short answer: The parabuntu kernel config has: ``` CONFIG_NFS_FS=y ``` Longer answer: Two files are sourced from be build scripts: https://github.com/parallella/parallella-linux/blob/parallella-linux-2016.11/arch/arm/configs/parallella_defconfig https://github.com/parallella/parabuntu/blob/master/kernel.config // Ola

Hmm, interesting. I'm not sure what to make of this in that case,

ben@parallella:~$ sudo apt-get install nfs-common

nfs-common is already the newest version.

Strangely enough, gunzip -c /proc/config.gz has no sign of CONFIG_NFS_FS whatsoever.

You're right! Turns out that CONFIG_NETWORK_FILESYSTEMS must be explicitly selected. Otherwise the nfs options will be ignored.

Fixed here:
parallella/parallella-linux@163953f

New uImage w/ nfs:
uImage.zip

Recipe:

1. Download uImage.zip
2. Unpack
3. scp uImage to parallella board
4. Copy to boot partition

parallella@parallella:~ $ sudo mount /dev/mmcblk0p1 /mnt
parallella@parallella:~ $ sudo cp uImage /mnt
parallella@parallella:~ $ sync
parallella@parallella:~ $ sudo umount /mnt

5. Reboot parallella

6. Install nfs-common:

$ sudo apt-get install nfs-common

Thanks!

Indeed this works; I'll allow you to close the ticket when this kernel goes into an official release.

Good to hear that,

Leave this open until the next Parabuntu release.
