Abstract

The invention discloses a method and a device for preventing split brain on the basis of a disk service lock, belongs to the technical field of computer cluster and is suitable for a high availability cluster. The method and the device for preventing the split brain on the basis of the disk service lock avoids the problem that when a cluster heartbeat network is interrupted, states of other nodes and operation service of the nodes cannot be judged accurately, service cannot be taken over, and the split brain is hard to avoid especially under the condition that the technology for restarting or storing and isolating a system is not used. The technical scheme includes: when the heartbeat network is interrupted, whether the heartbeat network is broken down or the nodes are halted is judged effectively; whether smooth stopping of service can be obtained correctly through inquiry of the disk service lock so as to avoid the problem of short split brain; a plurality of nodes grab the service lock simultaneously, only the successful node can start service to avoid split brain.

Description

(1) Technical field

[0001] The invention belongs to the technical field of computer clusters, is suitable for high-availability clusters, and is especially suitable for a method and device for split-brain prevention of a high-availability system based on disk service locks. (2) Background technology

[0002] With the rapid development of communication network technology, the requirements for server availability in key fields such as telecommunications, finance, and e-government are getting higher and higher, and high-availability cluster systems are increasingly accepted and widely used by more and more users. In order to avoid the huge economic loss caused by the failure of the server or switch, the high availability (High Availability, HA) system can greatly reduce the routine maintenance of the business system and the downtime of the business due to software and hardware failures. .

[0003] The current high-availability cluster system is mainly connected through the net...
