Problems solved by technology

[0002] In a distributed storage system, once hard disk data needs to be automatically restored due to disk failure, service restart, etc., it often takes up a lot of IO on the hard disk, affecting the response time of the current storage system for file reading efficiency, but the storage system itself cannot Adjust the frequency of data recovery, which will affect the normal access and use of users

Abstract

The invention relates to a data processing technology, and discloses a data recovery control method, a server and storage medium. The method comprises the following steps of: a server receiving a datarecovery request sent by the client, then, obtaining the IOPS of the server cluster to which the terminal belongs and the historical value of the throughput within the preset time, and calculating the predicted values of the IOPS and the throughput; judging whether the server cluster system is busy or not according to the predicted value and a preset rule; when the system is not busy; and according to the predicted value, calculating the data recovery concurrency number which can be increased to adjust the data recovery concurrency number of the server cluster, when the system is busy, adjusting the data recovery concurrency number of the server cluster according to a preset concurrency reduction rule, and performing data recovery on the storage nodes related to the data recovery request.By utilizing the method and the device, the technical problem that a large amount of IO is occupied during data recovery is solved, the normal operation of the system can be ensured, data copy loss can be prevented, and the risk of data loss is avoided.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data recovery control method, server and storage medium. Background technique [0002] In a distributed storage system, once hard disk data needs to be automatically restored due to disk failure, service restart, etc., it often takes up a lot of IO on the hard disk, affecting the response time of the current storage system for file reading efficiency, but the storage system itself cannot The frequency of data recovery is adjusted, which will affect the normal access and use of users. Contents of the invention [0003] In view of the above, the present invention provides a data recovery control method, server and storage medium. Its purpose is to flexibly adjust the data recovery method according to the current load of the system to ensure that the normal use of the system will not be affected. [0004] To achieve the above object, the present invention provides a data recover...
