Check that a glusterfs partition is mounted

When using glusterfs in a production system, it is mandatory to properly monitor that the partition is mounted and performing well, specially in heavy loaded environments.

I have created a nagios plugin in bash that monitors a glusterfs mounted partition and detects whether the partition gets unmounted, responds slowly or gets disconnected from the server (causing reading processes to die in an uninterruptible sleep state, which will force you to restart the system in order to get rid of them).
