Abstract
A system and method manages lock state information in a distributed file system. A meta-data volume includes a lock state database which is a comprehensive source for lock state information about a striped volume set in the system. A plurality of data volumes includes local lock caches which contain information about locks. Lock state messaging between the meta-data volume and the data volumes is used to assign locks and to update local lock caches. The meta-data volume is configured to assigned permissive areas in the data containers accessed by clients in order to efficiently manage the lock state information.
