Embodiment Construction

[0024] In many cases, such as the disconnection of the network cable, it is not necessary to directly restart the computer system, and after the computer system is started, the information must be re-initialized according to the requirements, which will be a time-consuming process and reduce efficiency.

[0025] In order to solve the above problems, the embodiment of the present invention provides a cluster split brain processing method and device, which can quickly detect and respond to split brain, stop shared resources on this node, stop business services provided by this node, and ensure the security of shared resources When the heartbeat of the node is restored, the service of the node can be restored directly, quickly and efficiently. It not only guarantees the safety of resources, but also improves the speed of cluster recovery and the performance of high-availability systems.

[0026] Embodiments of the present invention will be described in detail below in conjunction...

Abstract

The invention provides a cluster brain-split processing method and a device, relates to the field of computer technology application, which solves the problem that the brain-split processing mode is single, so that the cluster working efficiency is influenced. The method comprises the following steps that: each node in a cluster detects a heartbeat line between the node and other nodes in the cluster; when any heartbeat line cannot be detected in each node in the cluster, and the node stops the business on the node. The technical scheme provided by the invention is suitable for high-availability cluster, and realizes flexible and effective brain-split processing.

Description

technical field [0001] The invention relates to the application field of computer technology, in particular to a cluster split-brain processing method and device. Background technique [0002] High-availability cluster technology is widely used in the field of storage technology. In order to ensure the normal operation of the high-availability cluster, each node in the cluster needs to have normal activity when providing external services, so as to ensure stable external services. During the process of providing services by the cluster, due to changes in the environment, the nodes may fail in one way or another, causing the nodes to be disconnected from the cluster, resulting in a split-brain phenomenon. When a split-brain occurs, the services provided by the disconnected node may be abnormal now, causing the cluster to fail to work normally. Therefore, fast and accurate detection and response to a split-brain can improve the performance of the cluster. [0003] The existi...
