Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0029] A computer network composed of storage devices that provide the same storage service is called a storage cluster. Each of these physical devices is called a node. At the same time, the physical devices, software facilities, and network addresses on all nodes in this cluster are collectively referred to as cluster resources, referred to as resources for short, and the nodes where resources are located are also referred to as resource servers. In the present invention, in order to manage and switch these resources, a software facility is required to track, control and ...

Abstract

The invention relates to a method for realizing high-availability storage by using resource rings. The method forms multiple different resource rings among multiple nodes, and realizes the automatic switching of these resources on the resource rings through corresponding heartbeat technology to realize Storage high availability, including the following steps: 1) start the instance, each instance obtains the configuration file and reads it; 2) each instance obtains the network lock object, and sends an attempt to obtain the lock through the obtained lock object; 3) each instance judges whether to obtain Lock, if yes, then execute step 4), if not, then execute step 5); 4) The master instance continues to send heartbeat information with the set heartbeat interval, and starts and executes the configured resource services one by one; 5) Starts from the instance Timer, to determine whether to receive the heartbeat information sent by the master instance of the resource ring where it is located within the timeout period. Compared with the prior art, the invention has the advantages of saving investment, simple configuration and the like.

Description

technical field [0001] The invention relates to a storage backup technology, in particular to a method for realizing high-availability storage by utilizing a resource ring. Background technique [0002] As human life is more and more closely integrated with computers, the stable operation of computers determines the efficiency and quality of human production and life. Therefore, the stability of computers is a key factor, especially as one of the core components of computers. The storage system plays the role of storing data. Because all the components of the computer are designed to process, transmit, calculate, and use the data stored in the storage system. These data may be personal and corporate business data, financial information, customer information, operation logs, etc. Loss or temporary unavailability of these data may cause irreparable losses. [0003] However, as a single computer device, it always has natural and unsolvable defects and uncontrollable external ...
