Online 

Checks if nfsd and rpc.mountd daemons are running. If they are not running, the agent starts the daemons. 

Monitor 

Monitors versions 2 and 3 of the nfsd daemons, and versions 1 and 3 of the rpc.mountd daemon. Monitors TCP and UDP versions of the daemons by sending RPC (Remote Procedure Call) calls clnt_create and clnt_call to the RPC server. If the calls succeed, the resource is reported online. 

Clean 

Terminates and restarts the nfsd and rpc.mountd daemons.
