An upgrading method, equipment and cluster system

Abstract

The present invention provides an upgrade method, including: a third device divides the cluster into at least two sub-clusters, the at least two sub-clusters include an upgrade sub-cluster and a service sub-cluster, the upgrade sub-cluster includes at least one first device, and the service sub-cluster includes At least one second device; the third device instructs the upgrade sub-cluster to switch the first service it runs to the service sub-cluster so that the service sub-cluster runs the first service; the third device instructs the upgrade sub-cluster to upgrade at least one first device of the sub-cluster , so that the upgraded sub-cluster requests the service sub-cluster to switch the first service to the upgraded sub-cluster. The embodiment of the invention also discloses a device and a cluster system. Adopting the present invention can avoid the coexistence of new version equipment and old version equipment in a subcluster, and the mutual communication between subclusters can reduce the sending of messages between different subcluster equipment, thereby improving Upgrade efficiency.

Description

technical field [0001] The invention relates to the field of computers, in particular to an upgrading method, equipment and cluster system. Background technique [0002] During the operation of the storage system, upgrading the storage system can enable the storage system to obtain new functions and features. When upgrading, users usually choose to upgrade without interrupting services, so the storage system can only be upgraded online. [0003] The performance and storage capacity of the storage system can be superimposed and expanded through clustering. A cluster is composed of several devices. Take the cluster including device E1, device E2, and device E3 as an example. In the initial state, the performances of device E1, device E2, and device E3 are all old versions. In order to upgrade the cluster without interrupting services, only a part of the devices in the cluster can be selected for upgrading, while the other part continues to carry services. If the device E1 i...

Problems solved by technology

Since each device needs to be upgraded in this way, it will take a long time to complete the upgrade of all devices in the cluster. From the overall situation of the upgrade, the upgrade process is more complicated

[0004] In addition, the upgrade time of each device (about 10 to 20 minutes from upgrading the device to restarting the device) is long, which may easily lead to the coexistence of new version devices and old version devices in the cluster

For example, devices communicate with each other by sending a large number of messages. If device E1 is upgraded but device E3 has not yet been upgraded, the message sent by device E1 to device E3 is a message of a new version, but device E3 cannot recognize the new version. version information, causing the failure of normal communication between equipment E1 and equipment E3, thus affecting the online upgrade of the entire cluster, and even causing the operation of the cluster to fall into an abnormal state
