Monitoring Shared Storage

[Andy Shellam]

Hi Jay,

I assume your NFS server monitored by Nagios too?  If so can you monitor 
the disk/partition that /home on your servers point to on the NFS 
machine?  i.e. have a /home check_disk service configured in Nagios to 
your NFS server host.

You could then set all 50 other machines' /home services to have a 
service dependency on the /home service on your NFS host.  That way, if 
the service check on your 50 machines fails, Nagios will also check the 
/home service on your NFS host, and just send out the one notification.

Regards,

Andy
