Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a method and device for implementing distributed locks. By reading the corresponding part of the surviving nodes in the shared storage, the amount of data read is reduced, and the efficiency of implementing distributed locks is improved. The need to read all shared storage space causes waste of resources

Abstract

The invention discloses a method and a device for realizing a distributed lock. The invention relates to a cloud computing technology, which solves the problem of waste of resources caused by the needto read all shared storage space every time. The method comprises the following steps of: acquiring a surviving node in a current lock space; reading an I / O block corresponding to the surviving nodein the shared storage. The technical proposal provided by the invention is applicable to a large-scale cluster operation platform, and realizes the distributed lock with high efficiency and high resource utilization rate.

Description

technical field [0001] The invention relates to cloud computing 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-scale clusters are increasingly used in actual production environments. Through virtualization, a cloud computing platform is formed. In a virtualization system, when different systems or different hosts in the same system share the same resource or a group of resources, coordinated actions are often required, and mutual exclusion is often required to prevent mutual interference and ensure consistency, so distributed locks are required To ensure the normal operation of the system under the above circumstances. [0003] There are roughly two types of distributed lock implementation schemes: one implementation scheme is dependent on the network, and the consistency of obtaining resources is guaranteed through network commun...
