Embodiment 1

[0051] In specific implementation, in the above-mentioned multi-node cluster cross-upgrade method provided by the embodiment of the present invention, when performing software upgrade, as follows figure 2 As shown, before performing step S101 to select a node or some nodes in the cluster, it may also include:

[0052] S201. Upload the upgrade installation package to any node through the management interface (Web) or the secure shell protocol (Secure Shell, referred to as SSH); the upgrade installation package is used for software upgrades;

[0053] S202. Any node distributes the upgrade installation package to other nodes.

[0054] Next, step S101 is performed to select a node or a part of nodes among the nodes having mutual backup according to the node number, etc., and start the upgrade program.

[0055]Further, during specific implementation, in the above-mentioned multi-node cluster cross-upgrade method provided by the embodiment of the present invention, as follows fi...

Embodiment 2

[0076] In specific implementation, in the above-mentioned multi-node cluster cross-upgrade method provided by the embodiment of the present invention, when performing hardware upgrade, as follows image 3 As shown, before selecting a node or some nodes in the cluster, you can also include:

[0077] S301. Click hardware upgrade through the management interface.

[0078] Further, during specific implementation, in the above-mentioned multi-node cluster cross-upgrade method provided by the embodiment of the present invention, as follows image 3 As shown, after step S102 is performed to upgrade the program to leave the cluster, it may also include:

[0079] S302, shutting down the selected node;

[0080] S303. After shutting down, replace and upgrade the hardware;

[0081] S304. After the upgrade is completed, the selected node is powered on.

[0082] Furthermore, during specific implementation, in the above-mentioned multi-node cluster cross-upgrade method provided by the em...

Abstract

The invention discloses a multi-node cluster cross-upgrade method. The multi-node cluster cross-upgrade method includes the steps that one node or some nodes in a cluster are selected to start an upgrade program; nodes in the cluster are redundant and standby for another; the upgrade program is separated from the cluster to upgrade software or hardware, the other nodes, except selected nodes, take over the service of the selected nodes and provide service to the outside, and client multipath software completes a switch to the other nodes. In this way, by means of the multi-node redundancy design in the cluster and the mutual standby function of cluster nodes, uninterrupted online upgrading of services is achieved, update and upgrade of operating system level or hardware level is realized, extension of hardware and software functions is achieved, system maintainability and user experience are improved effectively and product competitiveness is increased.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method for cross-upgrading multi-node clusters. Background technique [0002] In modern storage software systems, the system itself is loaded with many services and needs to run non-stop. However, when the software is upgraded, the operating system and hardware are updated, and the nodes are regularly maintaining new functions, the services will be interrupted. It will have a certain impact on the storage software system. [0003] Therefore, how to realize online upgrade without service interruption is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method for cross-upgrade of multi-node clusters, which can realize online upgrade without service interruption, and expand software and hardware functions. The specific plan is as follows: [0005] A m...
