NFS locking and load balancing

Clustered Network File System (CNFS) supports a failover of all of the node’s load together (all of its NFS IP addresses) as one unit to another node. However, if no locks are outstanding, individual IP addresses can be moved to other nodes for load balancing.

CNFS depends on the domain name server (DNS) for any automated load balancing of NFS clients among the NFS cluster nodes. Using the round-robin algorithm is highly recommended.
