Shell Script for Nagios, checks if the FS given is mounted. Assumes that you are checking NFS by default, but it can check for any type of FS:

NFS, NFSv4, CIFS, JFS, JFS2, EXT2, EXT3, EXT4, etc (If a FS is mounted more than once it gives a Warning & reports the number of mounts).

This script do not check fstab or /etc/filesystem or other tab entries, as it is designed to consume as little CPU time as possible and to be used in different OS types.

It is a simple script, but it detects mounts of practically any type of FS, and multiple instances mounted of the same FS.

Verified compatible with the following OS:
IBM AIX v5.2-v7.2
RHEL v4.8-v6.6, RHL v9
Ubuntu v10.04-v18.04 LTS

SCO OpenServer v6.0.0
SCO UnixWare v7.1.4+, v7.1.4

Just works out of the box with minimal dependencies

Had to modify the script as shown below so that it wouldn't alarm if one mount was a subset of another (e.g. /mnt/foo and /mnt/foo_new would alarm, saying "/mnt/foo is mounted several times (2)"

Old line 107:
MOUNTED=`mount | grep $MOUNT | grep $FS | wc -l | tr -s " "` # execute the command to check the mount...

New line 107:
MOUNTED=`mount | grep "$MOUNT" | grep " $FS " | wc -l | tr -s " "` # execute the command to check the mount...
Owner's reply

Thanks for the bug report candreasen, I have modified the script with a bug correction and added a small CPU & memory speedup.

Note that your suggested line also won't work correctly in all OS, so i have only put one space after the FS, to act as a delimiter, and removed the space before the FS.

I will post the updated script now.
