Title:
DISTRIBUTED LOCK MANAGEMENT METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/190594
Kind Code:
A1
Abstract:
Provided in embodiments of the present invention are a distributed lock management method, device, and system. Nodes of a cluster storage system are divided into multiple groups, each group comprises a proxy node managing lock resources and a non-proxy node not managing lock resources, and the proxy node of each group manages a portion of all available lock resources. When a non-proxy node of a group desires to apply for lock permission, the non-proxy node applies to a proxy node of said group for same, and the proxy node of said group grants the lock permission to the non-proxy node of said group, such that the non-proxy node simply needs to know the proxy node in the group thereof and directly applies to the proxy node for lock permission without acquiring a lock directory. When a change of a non-proxy node of a group (for example, failure, recovery, etc.) occurs, arrangement of lock resources for nodes does not change, and thus updating a lock directory is not required unless a change of a proxy node occurs. In this way, the present invention improves availability of lock services.
