I got en email yesterday morning with the subject line - cron for user root /sbin/fstrim -a -v | logger &> /dev/null

 

and the message is - fstrim: /mnt/disks/Backup: FITRIM ioctl failed: No such file or directory

 

The only thing I think I may have changed in the last few days was updating the unassigned devices plugin (but may have updated a docker also).

 

I'm not really sure where to look for an issue, as the SSD Trim plugin has been installed and I've not messed with it for a LONG time, maybe years.

 

I don't believe I have, nor should have, a disk called Backup.  I have a share called Backup, set to use the cache, but not exclusively.

 

Diagnostics attached.

 

thanks for any help.

Something is showing as mounted there, likely a USB disk, if there's not a reboot will clear it.

Please don't cross post, closing this one.
