A fault-tolerant processing method, device, equipment and storage medium in data storage

Abstract

The application discloses a fault-tolerant processing method in data storage, including: calling the fault-tolerant processing process when the storage main process is running, and the fault-tolerant processing process and the storage main process are relatively independent and run in parallel; the IO generated during the storage main process is running Fault data and command fault data are monitored; when IO fault data or command fault data is monitored, the corresponding fault processing plan is searched in the preset fault processing plan library; the fault processing plan is executed. This application reduces the coupling degree between the fault-tolerant processing mechanism and the storage main process, not only improves the business operation efficiency of data storage, and makes the storage system more convenient for system upgrade and maintenance, but also effectively improves the concentration of the fault-tolerant processing process and efficiency, greatly improving the user experience. The present application also provides a fault-tolerant processing device, equipment and computer-readable storage medium in data storage, which also have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of fault tolerance, and in particular to a fault-tolerant processing method, device, equipment and computer-readable storage medium in data storage. Background technique [0002] Generally, storage systems in the prior art are designed with fault tolerance mechanisms during data storage. The system errors handled by the fault tolerance mechanism can be divided into two types, command data and IO data. During the operation of the main storage business, the upper-layer control module of the host sends command data, and after a certain intermediate processing process (such as protocol conversion or analysis, etc.), the bottom-level storage control module performs bottom-level processing to complete the data storage operation. However, the fault-tolerant processing program in the prior art is coupled to the intermediate processing of the main business process of the storage. Therefore, the interactive...

Problems solved by technology

However, the fault-tolerant processing program in the prior art is coupled to the intermediate processing of the storage main business process. Therefore, the interactive data between the upper control module of the host and the lower control module of the storage needs to be supervised by the fault-tolerant processing module. Not only seriously reduces the operating efficiency of the main storage business, but also the fault-tolerant processing program makes the executable program and additional program library of the storage system software huge, which is not conducive to system upgrade and maintenance
