<p class="MsoNormal">Before I start writing code that might be reinventing the wheel... does anyone have a favourite method for monitoring the presence of an NFS mount? <o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">check_disk is fine if the NFS volume is mounted and something goes wrong with it (like the NFS server going down) but gives a false positive if the volume simply isn't mounted. In that case it gives an OK result based on the closest enclosing
volume of the mount point.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">For example, if I'm using check_disk to monitor an NFS volume mounted at /mnt/foo, it will correctly fail if the remote NFS server stops responding, but will report success if I 'umount /mnt/foo'. In that case it'll report OK and give
the stats for the root ("/") volume.<o:p></o:p></p>
