Abstract

The invention discloses a cluster topology updating method, system and device and a computer medium, applied to a preset cluster node and used for receiving cluster link abnormal information sent by atarget cluster node. The method comprises the following steps: determining a to-be-deleted cluster node based on the cluster link exception information; deleting the to-be-deleted cluster node and the cluster link corresponding to the to-be-deleted cluster node in the cluster topology of the cluster to obtain an updated cluster topology, wherein the cluster link exception information comprises identification information of a target cluster node and identification information of an opposite-end cluster node connected with the target cluster node through the target cluster link; and the targetcluster link is an abnormal cluster link connected with the target cluster node. According to the cluster topology updating method and device, when the target cluster link connected with the target cluster node is abnormal, the target cluster node actively generates the cluster link abnormal information and sends the cluster link abnormal information to the preset cluster node, so that the presetcluster node can update the cluster topology based on the cluster link abnormal information, and the cluster topology updating efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of cluster storage, and more specifically, to a cluster topology update method, system, device and computer storage medium. Background technique [0002] Cluster storage is to aggregate the storage space in multiple storage devices into a storage pool that can provide a unified access interface and management interface for application servers. Applications can transparently access and utilize disks on all storage devices through this access interface, which can fully Play storage device performance and disk utilization. Data will be stored and read from multiple storage devices according to certain rules to obtain higher concurrent access performance. In the existing cluster storage system, when a link abnormality occurs in the cluster storage system, the master control node in the cluster storage system needs to determine which cluster nodes will have communication problems caused by the link abn...
