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 present invention provides a disk failure processing method, device and server of a distributed storage system, which relate to the technical field of computers and include: when an abnormal event triggering a data block is detected, sending a first response corresponding to the abnormal data block event to a management node remove the command to remove the data block information corresponding to the faulty data block stored in the management node; receive the second removal command sent by the management node; remove the data block information corresponding to the faulty data block stored in the data node, and based on The storage copy corresponding to the faulty data block shields the faulty data block. The invention can significantly reduce the influence scope of the data block failure, reduce the processing power of the disk failure, and effectively reduce the frequency of data recovery operation and data equalization operation.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method, device and server for processing a disk failure 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 information of disks in the distributed storage system (such as the existence of bad blocks in the disk, etc.) can be detected by deploying operation and maintenance tools. When the abnormal information of the disk is captured, the operation and maintenance tool will remove the disk , the data stored in the entire disk will become invalid due to the disk removal process caused by the bad block, which will lead to a large number of data recovery operations, and the disk after the disk removal process is equivalent to an empty di...
