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 commun...

Abstract

The invention provides an upgrading method. The method comprises a third device divides a cluster into at least two sub-clusters, wherein the at least two sub-clusters comprise an upgrading sub-cluster and a service sub-cluster, the upgrading sub-cluster comprises at least one first device, and the service sub-cluster comprises at least one second device; the third device instructs the upgrading sub-cluster to switch a first service operated by the upgrading sub-cluster to the service sub-cluster; the service sub-cluster operates the first service; the third device instructs at least one first device of the upgrading sub-cluster to upgrade; and the upgraded upgrading sub-cluster requests the service sub-cluster to switch the first service to the upgraded upgrading sub-cluster. The embodiment of the invention also discloses a device and a cluster system. Through adoption of the invention, a condition that a device of a new version and a device of an old version are concurrent in one sub-cluster can be avoided; message transmission among the devices of different sub-clusters can be reduced through intercommunication among the sub-clusters; and the upgrading efficiency is improved.

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...
