Subject: Monitoring NFS mounts
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?
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.
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.
