Cluster quorum method and multi-cluster cooperation system

Abstract

The embodiment of the invention discloses a cluster quorum method and a multi-cluster cooperation system. The method comprises the steps that whether a fault happens to a first cluster group or a second cluster group is detected, wherein the first cluster group comprises a part of a first cluster and a part of a second cluster, the second cluster group comprises the other part of the first cluster and the other part of the second cluster, and the first cluster and the second cluster cooperate with each other; when it is detected that the fault happens, the first cluster group and the second cluster group determine respective seizing representatives, and the seizing representative of the first cluster group and the seizing representative of the second cluster group each execute the following steps of determining whether the fault happens to the corresponding cluster group and seizing a quorum device if not, wherein the cluster group, which the seizing representative successfully seizing the quorum device belongs to, survives according to a preset quorum mechanism. By means of the cluster quorum method and the multi-cluster cooperation system, the probability of service access interruption can be lowered.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a cluster arbitration method and a multi-cluster coordination system. Background technique [0002] Active-active data centers mean that both data centers are running and can undertake business at the same time, improving the overall service capability and system resource utilization of the data center. The two data centers are mutual backups. When one of the data centers fails, there will be zero data loss, and the business can be automatically switched to the other data center. [0003] An active-active data center usually consists of a storage layer, a network layer, and an application layer. Several clusters are deployed in the active-active data center. Part of each cluster is located on one side of one data center, and the other part of each cluster is located on the other side of the data center. The sub-clusters of each data center work together . [0004] However, ...

Problems solved by technology

[0004] However, the arbitration mechanism of each cluster in the active-active data is different. When a failure occurs, each cluster adopts its own arbitration mechanism for arbitration, resulting in that the arbitration results of each cluster may not be consistent, that is, some clusters may be located in one of the data The sub-clusters in the center survive, some clusters in another data center survive, and then the entire business access is interrupted probabilistically
