AUFS pool disappeared after updates/reboot, unavailable now

theory · 27. Oktober 2016

I did some updates though the updatee manager and rebooted my NAS. When it rebooted I noticed Plex was not working. Upon further investigation I see that the hard drives are mounted, no issues with any of them, but the AUFS pool is unmounted. I'm not exactly sure how to remount it.

Do I need to un-reference everything first? Is there a proper way via cli?

You have to be more specific about what kind of updates if you are in Omv 3 with Jessie back port kernel there is no aufs driver anymore. Please post cat /etc/fstab

I used the update manager in the GUI and choose to upgrade all of them. I haven't updated to OMV 3.0, I'm still 2.2.12.

If you run "mount -a" does it give errors in terminal ?

theory · 27. Oktober 2016

This is the output of mount -a

Code

root@openmediavault:~# mount -a
mount: wrong fs type, bad option, bad superblock on none,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

subzero79 · 28. Oktober 2016

can you try

modprobe aufs

Then "mount -a"?

theory · 28. Oktober 2016

Same result

Code

root@openmediavault:~# modprobe aufs
root@openmediavault:~# mount -a
mount: wrong fs type, bad option, bad superblock on none,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might

I just found this thread: aufs problems

seems some other people have had a similar experience. Ran some updates, did a reboot, aufs volume no longer there. I saw someone there used : cat /var/log/syslog | grep aufs

I see they went through a process to fix it but I don't quite understand their steps. Is there an easy enough way to recreate a pool?

Code

Just edit the pool in the plugin. Also if you want you can switch to a better driver like mergerfs.

theory · 28. Oktober 2016

Edited the pool to use mergerfs, rebooted, and I can access my shares now!

A few other plugins not up and running yet like Plex, but I'm getting closer. Thanks subzero79
