Abstract

The invention discloses an OSD (object storage device) slow disk processing method, system and device and a computer storage medium and applies to distributed storage systems. The method comprises: acquiring attribute of a slow disk, and receiving a user's selection command; determining a processing mode of the slow disk according to the selection command; if the determined processing mode is a manual processing mode, generating a reminder message according to the attribute of the slow disk so that operation and maintenance staff may manually process the slow disk according to the reminder message; if the determined processing mode is an automatic processing mode, judging whether to adjust weight of an OSD corresponding to the slow disk to zero according to the selection command; if not, directly and automatically decreasing the weight of the OSD corresponding to the slow disk; if yes, judging whether it is possible to adjust the weight of the OSD corresponding to the slow disk to zero; if yes, adjusting the weight of the OSD corresponding to the slow disk to zero, and migrating original data in the slow disk having the weight zeroed to other OSDs in a cluster. The OSD slow disk processing method, system and device and the computer storage medium have the advantage that overall performance of a distributed storage system is improved.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to an OSD (object storage device, object storage) slow disk processing method, system, device and computer storage medium. Background technique [0002] In the era of cloud computing, users have higher and higher performance requirements for distributed storage systems. However, as the usage time of the distributed storage system increases, slow disks often appear in the distributed storage system, which makes the delay time of the distributed storage system longer and affects the user experience. Specifically, a slow disk refers to a disk with low read / write performance, whose read / write speed is much slower than other normal disks in the distributed storage system due to aging, voltage instability, or other mechanical reasons. When there is one or some slow disks in the distributed storage system, these slow disks become the short board of the entire distributed storage ...
