The drive referenced in the errors is the backup drive that was attached to the server for USB backup. The errors are referring to that drive which is now unmounted and disconnected.
I made changes to the openmediavault-filesystem.conf by commenting out the references to checking and mounting the missing filesystem...

This stopped the continuous errors... However after restarting monit, i am getting these errors every 8 minutes....

The USB backup interface has been configured with this particular drive as the "external storage device". So is this eight minute cycle normal to look for the connected USB device for backup?
