ABSTRACT:
A system and method manages lock state information in a storage system. A meta-data volume node includes a lock state database which is a comprehensive source for lock state information about data containers in the system. A plurality of data volume nodes include local lock caches, which contain information about locks. Lock state messaging between the meta-data volume node and the data volume nodes is used to assign locks and to update local lock caches. The meta-data volume node is configured to determine whether input/output requests should be allowed or denied and to instruct the data volume nodes of this input/output operation result. Lock information is also sent to the data volume nodes for storage in local lock state caches to the extent the data volume nodes have the network capacity locally.
