I am using the Dynamix SSD Trim tool to run trim on my cache at this time each evening. And each time it runs I get the following error (via email report): cron for user root /sbin/fstrim -a -v | logger &> /dev/null Console and webGui login account     fstrim: /mnt/cache: FITRIM ioctl failed: Remote I/O error Can anyone help me understand why the trim command is failing?
