NFS Locks

NFS locks allow a process to have exclusive access to all or part of a file. File locking is implemented both on the server and the client. When a file is locked, the buffer cache is not used for that file, and each write request is immediately sent to the server.

After a system failure, when the server is restarted, the server attempts to restore the file lock status to the previous condition. If the client fails, the server releases the file lock. However, after the client restarts it has a short period of time to reclaim the file lock.

To manage NFS locks

  1. On the primary navigation bar, choose Shares.
  2. Choose Sharing Protocols.
  3. Select NFS Protocol, and then choose Properties.
  4. Choose Locks.
  5. Optional: In the Current locks list, select the client whose locks you want to release.
  6. Optional: In the Wait period box, type the number of seconds after restarting that the server waits to re-establish a file lock with a client.
  7. Choose OK.
Note   NFS is available only if Microsoft Windows Services for UNIX Server for NFS is installed on this server. If NFS is not available on this server, this procedure is not applicable.
