Problems solved by technology

However, the faulty disk cannot be found in time and accurately, which seriously affects online services
Moreover, as far as China is concerned, medium-sized distributed storage disk failures are basically in the stage of manual processing, and they are completely repaired block by block manually, which consumes a lot of manpower and takes a long repair cycle, resulting in a long-term lack of data copies for some online data; and manual The repair method judges the disk failure state and the disk position is not accurate, which increases some unnecessary disk replacement costs; and the probability of manual operation error is high, threatening online services
Large-scale distributed storage such as Baidu Cloud, based on customized servers, has developed some low-level disk tools based on self-monitoring analysis and reporting technology SMART technology, which can be automatically repaired by the upper-level distributed system, but for different models and different storage services Fully automatic repair support is still not very good

Embodiment Construction

[0080] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention.

[0081] In order to achieve the above object, the present invention proposes a faulty disk detection and repair method, such as figure 1 As shown, the method includes steps S101-S103:

[0082] S101. Analyzing the name of one or more faulty disk devices according to the system log.

[0083] Optionally, the method also includes: when the disk fails, the faulty disk device where the faulty disk is located sends the status and operation report of the faulty disk device to the preset database server in real time; the preset database server reports the status and operation according to the status Generate disk failure information; and record the disk failure information in the system log.

[0084] Optionally, the status and opera...

Abstract

The invention discloses a failing disk detection and restoration method and a failing disk detection and restoration device. The method comprises the following steps: analyzing one or more failing disk equipment names according to system logs; locating and labeling each failing disk according to an analyzed failing disk equipment name and respectively detecting failure of each failing disk; and restoring each failing disk according to a failure detection result of each failing disk. According to the scheme, disk failure can be monitored in a real-time manner. Failing disks are located and automatically restored in a fast manner. Therefore, working efficiency is increased. The scheme supports a plurality of different server and storage businesses so that compatibility is raised.

Description

technical field [0001] The invention relates to the field of distributed storage, in particular to a faulty disk detection and repair method and device. Background technique [0002] At present, in large-scale (more than 20,000 directly connected disks) distributed back-end storage, disk errors occur on more than 10 disks every day. However, the faulty disk cannot be found in time and accurately, which seriously affects online services. Moreover, as far as China is concerned, medium-sized distributed storage disk failures are basically in the stage of manual processing, and they are completely repaired block by block manually, which consumes a lot of manpower and takes a long repair cycle, resulting in a long-term lack of data copies for some online data; and manual The repair method judges the disk failure state and the location of the disk is inaccurate, which increases some unnecessary disk replacement costs; and the probability of manual operation error is high, threate...
