Abstract

The invention discloses a slow disk detection method. The method comprises the steps of obtaining I / O time delay; And sending a disk self-checking command to a disk to facilitate self-checking of thedisk, and judging that the disk is a slow disk when the number of times of meeting a preset slow disk condition by the I / O time delay reaches a preset condition. According to the method and the device, the I / O time delay is firstly acquired, then the disk self-checking command is sent to the disk, the disk performs self-checking, and the disk is judged to be the slow disk only when the number of times of the I / O time delay meeting the preset slow disk condition reaches the preset condition, so that the slow disk judgment result is more accurate. In addition, the invention further provides a device and equipment with the advantages and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a slow disk detection method, device, equipment and computer-readable storage medium. Background technique [0002] When the disk has head degradation, disk aging, or other external factors, the disk will experience slow I / O response and performance degradation compared with other disks of the same model, and the disk will become a slow disk. [0003] In a disk storage array system, as long as there is a slow disk, it will affect the entire disk storage system, prolong the I / O response time of the disk storage array system, and reduce the performance of the entire system. Therefore, it is necessary to detect each disk to find out whether there is a slow disk in time. In the prior art, generally, the I / O response time exceeds a certain preset threshold as a determination condition. However, such a determination for a disk sometimes cannot accurately and effectively dete...
