Problems solved by technology

For concurrent access requests, only one can be accepted and processed, and other access requests will continue to be received after the processing is completed. A lock operation may require multiple access requests to complete, resulting in low file access efficiency

Abstract

The invention discloses a method and system for realizing a distributed lock manager. It involves virtual computing platform technology and solves the problem of low processing efficiency of concurrent access requests. The method includes: determining a corresponding receiving buffer queue when a distributed lock management operation is required; and exchanging distributed lock management operation information with the receiving buffer queue. The technical solution provided by the invention is applicable to the cluster file system, and realizes the distributed lock with high efficiency and high reliability.

Description

technical field [0001] The invention relates to virtual computing platform technology, in particular to a method and system for realizing a distributed lock manager. Background technique [0002] Since the cluster file system can be shared and mounted by multiple servers at the same time, in the field of server virtualization, the cluster file system will be used as a bridge between multiple computing nodes and centralized storage. The cluster file system can provide file concurrent access control, integrity assurance, and redundancy, etc., and is used by the virtualization system to store virtual machine images, shared storage pools, etc. The distributed lock manager (DLM) is a key component of the cluster file system and is used to manage concurrent access to shared resources; it mainly solves the problem of disk cache consistency between cluster nodes and improves the efficiency of shared file access . Common cluster file systems such as GFS, VMFS, OpenVMS Files, ocfs2,...
