Abstract

According to the distributed cluster online upgrading method disclosed by the invention, an upgrading scheme in which parallel and serial upgrading modes coexist after nodes in a cluster are grouped on the basis of services is provided, the nodes in the cluster are integrally divided, and the nodes without operating the services are divided into one group, namely, the service-free nodes; the method also includes dividing the clusters of the running business into one group, namely business running nodes; then, upgrading operation is executed on the non-service nodes which do not influence the cluster service at the same time, so that the upgrading occupation time is shortened, and the upgrading implementation rate is increased; executing the upgrading operation on the service operation nodes influencing the service one by one to ensure the normal operation of the cluster service, so that the method can improve the cluster upgrading efficiency of the storage system, shorten the time occupied by the upgrading process and ensure the normal operation of the cluster service. The invention further provides a distributed cluster online upgrading device and equipment and a readable storagemedium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of computer software, in particular to a distributed cluster online upgrade method, device, equipment and a readable storage medium. Background technique [0002] For distributed storage business clusters, it is often necessary to upgrade the cluster online while the cluster is running business. However, in order not to affect the normal operation of the cluster business, it is necessary to ensure that the decline in cluster business performance does not exceed a certain range. [0003] To achieve the above purpose, the serial upgrade method is usually adopted at present, that is, only one node in the cluster is upgraded at a time, and the upgrade of the next node can only be continued after the upgrade of the current node is completed and the cluster status returns to normal. In this upgrade method, all nodes can only be upgraded one by one, and the upgrade efficiency is very low; and as the clust...
