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

Abstract

The invention discloses an online upgrade method for an uninterrupted storage cluster node, comprising: after a master node receives an upgrade instruction, it creates and runs a software upgrade transaction of the cluster; during the running process of the software upgrade transaction, according to a preset upgrade rule, sequentially controls the Each node of the cluster is upgraded; during the cluster upgrade process, the upgraded nodes in the cluster downgrade the data packets to be sent to the data packets of the version before the upgrade and then send them to other nodes; after the cluster upgrade is completed, all nodes in the cluster follow the Later versions of datagrams are used for communication. The invention can upgrade the cluster without interrupting the business, and can overcome the problem of inconsistency of data message versions in the non-interrupted upgrading, so as to ensure the normal operation of the business. The invention also discloses a device, equipment and computer-readable storage medium based on the above method.

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. [00...
