Re: Monit not picking up when usb drive unmounts itself

[Jan-Henrik Haukeland]

The solution is kind of hidden in the manual [1] (unfortunately), but the short 
answer is, monitor the device not the mount-point, because if the disk 
“unmounts" the mount point will still be there right? 

So you need to figure out which device is behind your (cool) mount-point names, 

So instead of 

check filesystem snake-pliskin with path /mnt/snake-pliskin
     start program = "/bin/mount /mnt/snake-pliskin"
     stop program = "/bin/umount /mnt/snake-pliskin”

instead use 

check filesystem snake-pliskin with path /dev/some-usb-device
     start program = "/bin/mount /mnt/snake-pliskin"
     stop program = "/bin/umount /mnt/snake-pliskin”
