Embodiment 2

[0053] see figure 2 , figure 2 It is a flow chart of another storage cluster online upgrade method provided by the embodiment of the present application. Before the upgrade, in order to avoid confusion in the upgrade process, all nodes in the storage cluster can be divided into groups of two nodes and labeled, and then the private status information of each group of corresponding nodes can be upgraded in sequence of numbers. The corresponding technical solutions are as follows:

[0054] S201: Compile the cluster sharing information of the nodes in the storage cluster in the form of a dynamic link library;

[0055] S202: Divide and label all nodes in the storage cluster into groups of two nodes;

[0056] The two nodes here may be adjacent nodes or functionally similar nodes. The purpose of grouping is to prevent the storage cluster from being confused due to the upgrade, so that the upgrade progress of different nodes is different. After grouping, the system upgrades in ...

specific Embodiment approach

[0061] see image 3 , image 3 It is a flow chart of another method for online upgrade of storage cluster provided by the embodiment of the present application. This embodiment is a specific implementation of online upgrade of storage cluster. The technical solution is as follows:

[0062] S301: Construct the system installation package, and upload the installation package to the configuration node interacting with the user in the storage cluster to prepare for upgrading;

[0063] The system installation package includes information required for storage cluster upgrade, that is, cluster shared information and private state information of all nodes, and of course other information may also be included. System installation packages exist in mirror or other forms.

[0064] S302: Compile the cluster sharing information of the nodes in the storage cluster in the form of a dynamic link library;

[0065] The cluster shared information exists in the form of a dynamic link library. ...

Abstract

The invention discloses a storage cluster online upgrading method. The method comprises the steps of compiling cluster sharing information of nodes in a storage cluster in a dynamic link library form; upgrading private state information of the nodes; and after the private state information corresponding to all the nodes is upgraded, upgrading the cluster sharing information of all the nodes at the same time. The cluster sharing information of the nodes in the storage cluster is compiled in the dynamic link library form, and non-interfering upgrading of the cluster sharing information and the private state information of the nodes is realized, so that online upgrading of the whole storage cluster is realized. According to the storage cluster online upgrading method provided by the invention, relatively few objects need to be cooperated in the upgrading process; and the upgrading process is simpler. The invention furthermore provides a storage cluster online upgrading system, which has the abovementioned beneficial effects.

Description

technical field [0001] The present application relates to the technical field of SAN storage, in particular to a storage cluster online upgrade method and system. Background technique [0002] SAN (full name in English: Storage Area Network, Chinese name: Storage Area Network) adopts mesh channel technology, connects storage arrays and server hosts through FC switches, and establishes an area network dedicated to data storage. [0003] A storage cluster aggregates the storage space in multiple storage devices into a storage pool that can provide a unified access interface and management interface for application servers. Applications can transparently access and utilize the disks on all storage devices through this access interface, which can fully Play storage device performance and disk utilization. Data will be stored and read from multiple storage devices according to certain rules to obtain higher concurrent access performance. [0004] In the customer scenario, there...
