Problems solved by technology

At present, related technologies propose that the abnormal disk information (such as bad blocks in the disk, etc.) in the distributed storage system can be detected by deploying operation and maintenance tools. When the disk abnormal information is captured, the operation and maintenance tool will perform disk processing on the disk , for the off-disk processing caused by bad blocks, the data stored on the entire disk will be invalidated, which will cause a large number of data recovery operations, and the disk after the off-disk processing is equivalent to an empty disk. If there is data in other disks in the distributed storage system, Will adversely affect the balance of the distributed storage system

Abstract

The invention provides a disk fault processing method and device of a distributed storage system and a server, and relates to the technical field of computers, and the method comprises the following steps: when a data block exception triggering event is detected, sending a first removal command corresponding to the data block exception event to a management node, data block information corresponding to the fault data block stored in the management node is removed; receiving a second removal command sent by the management node; and removing data block information corresponding to the fault data block stored in the data node, and shielding the fault data block based on the storage copy corresponding to the fault data block. According to the method, the influence range of data block faults can be remarkably reduced, the processing strength of disk faults is reduced, and the frequency of data recovery operation and data balancing operation is effectively reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a disk failure processing method, device and server of a distributed storage system. Background technique [0002] A distributed storage system is a system that buffers local data by dispersing and storing data on multiple independent devices, thereby reducing network pressure. At present, related technologies propose that the abnormal disk information (such as bad blocks in the disk, etc.) in the distributed storage system can be detected by deploying operation and maintenance tools. When the disk abnormal information is captured, the operation and maintenance tool will perform disk processing on the disk , for the off-disk processing caused by bad blocks, the data stored on the entire disk will be invalidated, which will cause a large number of data recovery operations, and the disk after the off-disk processing is equivalent to an empty disk. If there is data in othe...
