Cache partition management method, system and equipment and storage medium

Abstract

The invention discloses a cache partition management method. The method comprises the following steps: receiving an event notification sent by a cluster; after information which is fed back by the service end and indicates that the task corresponding to the last event notification is executed completely is received, updating node information of the cache partition according to the last event notification, and sending the task corresponding to the current event notification to the service end; and after information which is fed back by the service end and indicates that the task corresponding to the event notification is executed completely is received, updating the node information of the cache partition according to the event notification. By applying the scheme provided by the invention, the situation that the node information of the cache partition is abnormal can be avoided. The invention further discloses a cache partition management system and equipment and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a management method, system, device and storage medium of cache partitions. Background technique [0002] With the current higher and higher requirements for storage, high-performance clusters composed of multiple nodes have been more and more widely used. [0003] In practical applications, especially in the single-partition mode, sometimes the node information of the cache partition is abnormal. For example, the cache partition that should exist only on one node will exist on both nodes of an IO group. Furthermore, when deleting the cache partition, only the cache partition on one node is deleted, and the cache partition on the other node still exists, which leads to problems in business configuration. Moreover, most of such situations occur during the T2 failure recovery process of the cluster. T2 failure means that each node in an IO group exits the cluster at the ...

Problems solved by technology

[0003] In practical applications, especially in the single-partition mode, sometimes the node information of the cache partition is abnormal. For example, the cache partition that should exist only on one node will exist on both nodes of an IO group. In turn, when deleting the cache partition, only the cache partition on one node is deleted, and the cache partition on the other node still exists, which leads to problems in business configuration

Moreover, most of this situation occurs during the T2 failure recovery process of the cluster
