Abstract: Methods and systems for handling lock state information between a first storage system node and a second storage system node coupled via a network link are provided. The second storage system node stores lock state information at a storage device previously managed by the first storage system node and notifies the first storage system node of a storage device location where the lock state information is stored. The second storage system node then transfers ownership of the storage device to the first storage system node that copies the lock state information from the storage device location to a memory location managed by the first storage system node. The first storage system node uses the lock state information to reconstruct any locks for storage space presented to a client and then processes client requests for reading and writing information at the storage device.
