Abstract
A system and method for implementing clustered network file system lock management is provided. A failure of a first server node among a collection of nodes is detected. The first server node includes lock status data. The lock status data grants a first client exclusive access to data stored on a server storage device. The server storage device is coupled to the collection of server nodes. The lock status data is transferred to a second server node among the collection of server nodes. The first client is granted exclusive access to data stored on the server storage device, based on the lock status data transferred to the second server node from the first server node, in response to the transferring. Lock requests from the collection of clients are accepted, in response to the transferring.
