I received this error the other night via email from my unraid server:
 

cron for user root /sbin/fstrim -a -v | logger &> /dev/null

fstrim: /etc/libvirt: FITRIM ioctl failed: Input/output error

 

When I this the next day I logged in but my dockers have all disappeared.  I tried rebooting, turning dockers on/off.

I attempted to run a Restore using a backup from a few days before the error using CABackupRestore, but when doing so rootfs (32G) fills up and then the system is unusable until I reboot via CLI.

 

This time when running the Restore I got the following via email:

This makes no sense at all.  Reboot

Lots of things go bad when OS has no free space to work in.

Reboot

 

Did a reboot but still no dockers.  I just looked in my appdata folder which is showing empty.

Now I'm looking further and noticed my cache drive disappeared.  That may have been the issue with the trim error above.  

I connected my cache drive to my windows pc using an external hdd enclosure but nothing coming up. Would I be able to see or test the drive in windows or does Unraid have it in a special format where I wouldn't be able to check?

Windows can't read any Unraid filesystem.

 

Attach new diagnostics to your NEXT post in this thread.

So attached are the new diagnostics. I pulled these after I did the following.  I put in a new SSD of the same size and it was recognized on the 2nd reboot.  I ran the CA Restore which ran successfully and did not fill the rootfs.  appdata folder is now populated again.  

Problem still occurring is my VM and dockers are still missing.

Think I got this figured out now.  Had to reload the templates I had saved for each docker container.  Probably going to have to check my settings in each docker as well but so far it is looking better.  I think there may have been an easier way to do this when swapping the cache but i could be wrong.

 

I appreciate the quick responses though guys, thank you.
