NFSRestart agent

The NFSRestart agent provides the following functionalities:

Manages NFS lock recovery service by recovering the NFS record locks after sudden server crash.

Prevents potential NFS ACK storms by terminating NFS server services before offline of NFS VIP to close all TCP connections with the NFS client.

If you have configured the NFSRestart agent for lock recovery, the NFSRestart agent starts the smsyncd daemon. The daemon copies the NFS locks from the local directory /var/lib/nfs to shared storage. The agent's online function copies the locks from shared storage to local directory /var/lib/nfs.
