The Sun Cluster HA for NFS fault monitor probe monitors the success or failure of file sharing by monitoring the following files:
/etc/dfs/sharetab
/etc/mnttab
Pathprefix/SUNW.nfs/dfstab.resource
The Pathprefix part of the file path is the value of the Pathprefix extension property for the resource group, and resource is the resource name.
If the probe detects any modification to any of these files, it shares the paths in dfstab.resource again.
