Agent functions for NFS agent

Online

Starts NFS services on the system. For NFSv3, the services also include NSM (Network Status Monitor) and NLM (Network Lock Manager) service. If NFSv4 is enabled, it also starts NFSv4 name mapping daemon

Monitor

Monitors the NFS services running on the system. For NFSv3, it checks for version 2 and version 3 of NFS service along with other NFS services. For NFSv4, it also checks the availability of NFSv4 name mapping daemon.

Clean

Stops and restarts NFS services for all kernels. It also stops and restarts NSM and NLM services running on the system.

Attr_changed

When the Protocol attribute is changed, this function dynamically restarts the NFS services if the services are not running as per the protocol specified in the Protocol attribute.
