Abstract
A system and method persistently stores lock state information associated with a file system within a storage system. Received operations that modify lock state information are stored in a non-volatile log (NVLog) within a non-volatile random access memory (NVRAM) of the storage system. During a consistency point (CP), entries from the NVLog are committed to a lock file. In the event of an error condition, lock state information may be recovered from the lock file, thereby enabling rapid reconstruction of the lock state prior to the error condition.
