Abstract

The embodiment of the invention discloses a distributed storage system reconstruction method, a device, equipment and a storage medium. The reconstruction method comprises the steps: obtaining a safety load value of a system based on a first load value of the system, the first load value at least comprises a maximum bearing load value of the system in a first period, a service load peak value of the system in the first period and a service load average value of the system in the first period; and determining reconstruction information of the system based on the safety load value and/or the service load average value. The problem of how to avoid the influence on the front-end service when the system is reconstructed is solved, and the purpose of automatically adjusting the reconstruction information is achieved. Meanwhile, the reconfiguration device of the distributed storage system does not need to judge the service trough period, the system can be reconfigured according to reasonable reconfiguration information, and the purposes of increasing the reconfiguration speed and shortening the danger period of the system are achieved.

Description

technical field [0001] The present application relates to the technical field of cloud computing, and in particular to a reconstruction method, device, equipment and storage medium of a distributed storage system. Background technique [0002] With the advent of the cloud computing era, various cloud computing solutions emerge in endlessly. Among them, the distributed storage system is the most important part of the cloud computing system, because it carries the data services of the entire system, and the impact of a small problem in the distributed storage system on the entire cloud computing system is difficult to estimate. Distributed storage systems usually adopt a multi-copy strategy. When a storage disk or storage node fails, the lost copy can be reconstructed on other disks or nodes in the cluster through the remaining copies, thus preventing data loss when the system fails. However, data reconstruction will consume a large amount of disk IO (Input Output, input and ...
