Problems solved by technology

In the active-standby disaster recovery solution, only the primary storage server can read and write data, and the standby storage server can read data but not write data. When the primary storage server fails, only data reading can be performed. Normal service, the data writing request cannot be executed, which will affect the normal operation of the data business

Abstract

The embodiment of the invention discloses a disaster recovery method of a storage system. The disaster recovery system comprises a plurality of storage servers with data reading and writing functions,the method comprises the steps that a first storage server in the storage system receives a first data writing request sent by a service server, and after the first storage server completes data writing according to the first data writing request, a data synchronization request is sent to a second storage server; wherein the second storage server is other servers except the first storage server in the plurality of storage servers, and the data synchronization request is used for indicating the second storage server to complete data writing according to a first data writing request when receiving the first data writing request sent by the service server after completing data synchronization. By adopting the embodiment of the invention, the condition that the storage server of the storage system can only read and cannot write when sending a fault can be optimized, and data reading and data writing services can still be provided under the condition that any storage server in the storagesystem has a fault.

Description

technical field [0001] The present application relates to the field of information technology, and in particular to a storage system disaster recovery method, device, equipment and computer-readable storage medium. Background technique [0002] In the era of rapid development of information technology, effective storage of data is particularly important for all walks of life. Disaster recovery is a very critical link in storage system design. Its purpose is to prevent catastrophic emergencies such as data loss or interface unavailability due to machine failures, and to ensure uninterrupted operation of data services. [0003] In existing disaster recovery design schemes of storage systems, an active-standby disaster recovery scheme is often used. In the active-standby disaster recovery solution, only the primary storage server can read and write data, and the standby storage server can read data but not write data. When the primary storage server fails, only data reading ca...
