Problems solved by technology

Some split-brain phenomena may be due to the unstable network connection status of the storage cluster, resulting in temporary disconnection of the connection between some storage devices and the storage cluster. In order to enable these temporarily disconnected storage devices to be connected to the storage cluster as much as possible, In the existing technology, the detection is usually repeated several times. If the heartbeat information from a certain node is not received several times in a row, the node will be disconnected. Therefore, a method can be proposed to improve the stability of the network connection of the storage cluster , effectively prevent split-brain, and provide arbitration services in time after split-brain

Abstract

The invention discloses a method and a system for realizing storage cluster arbitration and computer equipment. The method comprises the following steps executed at an arbitration control end: establishing network communication connection with a storage cluster; monitoring a network communication connection state with a storage cluster according to the heartbeat message; if the network communication connection state with the storage cluster is monitored to be a disconnected state, sending a reconnection request to the storage cluster so as to reestablish network communication connection with the storage cluster; if the network communication connection with the storage cluster is not re-established, recording the number of reconnection times, determining a time period based on the number of reconnection times, and sending a subsequent reconnection request to the storage cluster according to the time period so as to re-establish the network communication connection with the storage cluster; and in response to the change of the view of the storage cluster, receiving an Allegiance request sent by the storage node and performing arbitration. Through the scheme of the invention, the split-brain phenomenon caused by the unstable network connection state of the storage cluster is solved, and the stability of the storage cluster is improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method, system and computer equipment for realizing storage cluster arbitration. Background technique [0002] With the development of society, enterprises have higher and higher performance requirements for storage devices, and it is difficult for a single storage device to meet the performance requirements of enterprises. In this case, multiple storage devices should be combined to form a storage cluster, and one storage cluster will provide external services in a unified manner. Storage clusters can greatly improve the processing power and availability of storage devices. However, when a storage cluster encounters a link failure, the storage devices in the storage cluster will be invisible to each other, causing a storage cluster to split into two or more storage subclusters. can communicate with each other, but storage devices in two different storage subclusters ...
