I am having issues with my shares "suddenly" disappearing and all my Docker containers crashing because of it. After a reboot the shares re-appear for a couple of days before crashing again.

When navigating to 'shares' I get: "There are no exportable user shares". When I check the files directly it seems that they are still available.

I am kind of lost on where to begin, so I hope that the diagnostics can provide an answer.

plexparasieten-diagnostics-20260820-0953.zip

The diagnostics confirm that this is the main user-share shfs process disappearing at runtime, rather than the disks or pools becoming unavailable.

Both /mnt/user0 and /mnt/user mounted normally after boot. In the failed-state diagnostic, all eight array disks and both pools are still mounted, and /mnt/user0 still has its shfs process. The separate shfs process for /mnt/user is no longer present.

Unfortunately, the logs do not contain the event that made shfs exit. There is no logged shfs crash, OOM kill, clean unmount, filesystem error, or disk/controller failure. Therefore, we can confirm the failure mechanism but not yet whether it is an internal shfs problem, an external process killing it, or another system-stability issue.

If you haven't yet rebooted, please provide the output of:

ps -ef | grep '[s]hfs'

findmnt -rn -M /mnt/user

findmnt -rn -M /mnt/user0

grep -E ' /mnt/user(0)? ' /proc/self/mountinfo

timeout 5 stat /mnt/user

dmesg -T | tail -n 300

A Safe Mode run lasting longer than the normal recurrence window would also help determine whether a third-party plugin, background directory scanner, or User Script is involved.

Thanks for the answer!

Thanks, this output confirms the failure state.

/mnt/user mount is still present in the mount table, but its corresponding shfs process is no longer running. This is why access to /mnt/user returns Transport endpoint is not connected. The separate /mnt/user0 mount and its shfs process remain operational.

Unfortunately, the kernel log still does not show why the /mnt/user process disappeared. There is no shfs or FUSE error, OOM kill, kernel fault, clean unmount, or storage failure around the event.

You can reboot to restore the user shares. For the next troubleshooting step, recommend booting in Safe Mode and operate the server for longer than its usual recurrence period. This will help determine whether a third-party plugin, User Script, or background scanner is involved.

Also ensure persistent logging is written to a remote syslog server or another destination that does not depend on /mnt/user. If the problem happens again in Safe Mode, capture fresh diagnostics before rebooting. If it remains stable, re-enable third-party plugins in small groups until the failure returns.

Were you able to confirm if this still happens in safe mode and/or get new logs of more events?
