Embodiment Construction

[0068] Take two nodes A and B as an example to form a cluster. A service is running on A, and B is used as the standby machine. When node B finds that it cannot communicate with A, if it guesses that it is a network failure, then B will keep the standby role unchanged. However, if the A node is actually faulty, the cluster will lose its active use, and the upper-layer applications cannot continue to run. Conversely, if node B guesses that node A is faulty, then B will take over from A to run the service. However, if it is only a network failure and A is still running normally, there will be two master machines A and B in the cluster. The situation of multiple host machines is also something that clusters need to try their best to avoid, because multiple host machines compete with each other for resources, which may lead to data corruption in severe cases.

Abstract

The present invention provides a method and device for processing brain split in cluster. The method and device for processing brain split in cluster relate to the field of the computer application, and solve the control problem after brain split in cluster. The method provided by the invention, when the brain split occurs in cluster, the only one subset allowed to continue the service is selected in the cluster; nodes in other subsets except the only one subset allowed to continue the service are controlled to stop working. The technical scheme provided by the invention is applicable to the computer cluster, and the orderly management of the cluster in the condition of the brain split in cluster is realized.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a cluster split-brain processing method and device. Background technique [0002] High availability cluster is a server cluster technology aimed at reducing service interruption time. The node on which the service is running is called the master. The node that is not running the service but may take over from the main machine to run the service is called the standby machine. When the primary machine fails, the standby machine will take over and continue to run the service, achieving the effect of providing continuous service. [0003] The interconnection network between nodes is called a heartbeat. Through the heartbeat line, each node in the cluster can communicate with any other node, and through the communication protocol, it can also know which nodes are in the current cluster (the module providing communication function will be referred to as "heartbeat communication ...
