Abstract

A business recovery method, device, arbitration server, and storage system, the method comprising: after the storage system switches from a dual-slave state to a fault recovery state, the first storage array first sends a first arbitration request to the arbitration server, and when the arbitration server receives After the first arbitration request sent by the first storage array, determine the first arbitration result of the first storage array and the second arbitration result of the second storage array, after determining the first arbitration result and the second arbitration result Afterwards, the first arbitration result is sent to the first storage array and the second arbitration result is sent to the second storage array. After receiving the first arbitration result, the first storage array initiates a negotiation with the second storage array to determine the negotiation result. If the negotiation result is determined to be the winning state of the first storage array and the second storage array is If the losing state fails, the first storage array provides business services to the client.

Description

technical field [0001] The present application relates to the technical field of storage, and in particular to a service recovery method, device, arbitration server and storage system. Background technique [0002] With the advent of the Internet age, the business needs of all walks of life are increasing. In order to ensure the reliability of the service, an active-active storage system is used to provide cloud computing services. [0003] Please refer to figure 1 , is a schematic structural diagram of the active-active storage system. Such as figure 1 As shown, the active-active storage system includes a quorum server and two storage arrays (storage array A and storage array B) that are mutually backed up. When the active-active storage system is running normally, both storage arrays are running, and services are provided by the two storage arrays at the same time. When storage array A loses power or equipment failure occurs, resulting in inability to process business...
