I recently switched from AUFs to Mergerfs for Union File System. Over a week span, I had two instance where the file system shutdown. If I was to go to "Physical Disk" it would show all of the drives as N/A. None of the applications that used those UFS disk would work until I rebooted. After digging into the syslogs, I found the following.
May 23 20:45:01 OMV /USR/SBIN/CRON[11560]: (root) CMD (/usr/sbin/omv-mkgraph >/dev/null 2>&1)

All SMART test on HDDs are showing good health. Does anyone have any direction I could go with this one?
