Abstract

The invention discloses a distributed lock realization method and device. It involves the field of virtualization of computing resources, and solves the support problem of storage pool lock resources. The method includes: identifying the type of the current storage pool; selecting an execution mode according to the type of the current storage pool; and completing reading and writing of the distributed lock in the selected execution mode. The technical scheme provided by the invention is suitable for computer clusters, and realizes distributed locks compatible with various storage pools.

Description

technical field [0001] The invention relates to computing resource virtualization technology, in particular to a distributed lock implementation method and device. Background technique [0002] With the rapid development of computer technology and network technology, large clusters have been widely used in actual production environments. By virtualizing the cluster, a cloud computing platform is formed. In a virtualization system, it is often necessary to coordinate actions, and different systems or different hosts in the same system share the same resource or a group of resources. When sharing resources, mutual exclusion is often required to prevent mutual interference and ensure consistency, so distributed locks are needed to ensure the above situation. [0003] Distributed locks generally need to support the use of distributed locks in large-scale environments, so sanlock is used to manage resources in virtualization systems. For sanlock, there are generally two ways t...
