Uninterrupted storage cluster node online upgrading method, device and equipment

Abstract

The invention discloses an uninterrupted storage cluster node online upgrading method which comprises the following steps: after a master node receives an upgrading instruction, creating a software upgrading transaction of a cluster and operating the software upgrading transaction, and sequentially controlling each node in the cluster to upgrade according to a preset upgrading rule in the softwareupgrading transaction operating process; In the cluster upgrading process, the node which completes upgrading in the cluster downgrades the data message to be sent into a data message of a version before upgrading and then sends the data message to other nodes; And after the cluster is upgraded, all the nodes in the cluster communicate according to the upgraded version of the data message. According to the invention, cluster upgrading can be carried out under the condition that the service is not interrupted, the problem that the versions of the data messages are inconsistent during uninterrupted upgrading can be solved, and the normal operation of the service is ensured. The invention further discloses a device and equipment based on the method and a computer readable storage medium.

Description

technical field [0001] The invention relates to the technical field of cluster upgrades, in particular to an online upgrade method for non-interrupted storage cluster nodes. The present invention also relates to an online upgrade device, equipment and computer-readable storage medium for non-interrupted storage cluster nodes. Background technique [0002] With the diversity and rapid iteration of data center services, the storage system needs to be continuously upgraded to meet the business needs of users, and then the upgrade will inevitably interrupt the business. How to minimize the impact of business interruption has always been a research direction in the storage field. However, some specific application scenarios do not allow service interruption. Therefore, in these application scenarios, the upgrade cannot be performed during service operation, which affects the normal upgrade process of the storage system; therefore, non-disruptive online upgrade is required.

AI Technical Summary

Problems solved by technology

During the non-interrupted online upgrade process, due to the inconsistent upgrade completion time of each node, the version of the data message sent by the node after the upgrade is inconsistent with the version of the data message sent by the unupgraded node, which will cause the receiving node to It will not be able to correctly parse the message information of the peer node, which will affect the normal operation of the business
