Network Lock Manager and NFS

The Network Lock Manager provides UNIX record locking for any files being shared over NFS. The locking mechanism enables clients to synchronize their I/O requests with other clients, ensuring data integrity.

Note -  The Network Lock Manager is used only for NFS Version 2 and NFS Version 3 mounts. File locking is built into the NFS Version 4 protocol.
