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
SuSe v11
CentOS v6.5-10
CygWin v2.0.4-v2.5.1 & BusyBox v1.22.1
Oracle Solaris x86 v10-v11.3
SCO OpenServer v6.0.0
SCO UnixWare v7.1.4+, v7.1.4
Released under GPLv3. Author: Carlos Ijalba - 2016-2018.
Shell Script for Nagios, checks if the FS passed on $1 is mounted under Mount Type $2.
If no parameter passed on $2 NFS type is assumed by default.

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.
