Linux Check Mounted Disks Nagios Plugin
For my own use as much as anyone elses… One of the problems that’s haunted me at least once per company I’ve worked at as a tech is “the disappearing partition”. It’s there, it’s accessible, and it should be persistent across boots. But it isn’t! The machine reboots and then you discover that the database partition is no longer visible.
The check mounted
disks Nagios plugin looks at the mounted partitions and compares them
to what’s in
/etc/fstab (minus a couple of things like cd
drives, floppy disks, swap partitions etc). And warns if there are any
discrepancies that’ll bite you on a reboot. It also round trips and makes
/etc/fstab thinks is mounted is actually there.
