Network File System (NFS) allows network users to access shared files stored on an NFS server. NFS allows you to manage shared files transparently as if the files were on a local disk. For more information about NFS and configuring NFS service groups, refer to the following sections:
The NFSRestart agent is a Cluster Server (VCS) bundled agent. This agent is installed on the system when you install VCS. The NFSRestart agent is configured in conjunction with the NFS agent for failover type shared service groups.
The NFSRestart agent manages essential NFS locking services, network status manager, and network lock manager. The agent also manages NFS lock recovery service by recovering the NFS record locks after sudden server crash. The agent prevents potential NFS ACK storms by terminating NFS server services before closing all Transmission Control Protocol (TCP) connections with the NFS client.
