Embodiment Construction

[0073] The embodiment of the present invention provides a slow disk detection method and system, which are used to detect the slow disk phenomenon in the hard disk by adopting the method of random detection and partition detection, and only when the duration of the slow disk phenomenon exceeds the preset threshold Determining that the hard disk is a slow disk improves the accuracy rate of slow disk detection and reduces the rate of missed judgment and misjudgment rate of slow disk detection.

[0074] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is an embodiment of a part of the present invention, but not all embodiments. Based on the embodiments of the present invention, all o...

Abstract

The embodiment of the invention discloses a slow disk detection method and a slow disk detection system, which are used for improving the accuracy of slow disk detection and reducing the missed judgment rate and the misjudgment rate of slow disk detection. The method provided by the embodiment of the invention comprises the following steps: acquiring IO performance indexes of a hard disk, whereinthe IO performance indexes at least comprise random input / output IO response time of the hard disk and input / output IO response time of each preset partition of the hard disk; judging whether the IO performance index of the hard disk is abnormal or not; if yes, recording the duration time of the abnormality and / or the duration times of the abnormality in a preset time; respectively judging whetherthe duration time and / or the duration frequency are / is greater than a corresponding preset threshold value or not; and if so, determining that the hard disk is a slow disk.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a slow disk detection method and system. Background technique [0002] Due to the degradation of the magnetic head or other mechanical and environmental problems of the hard disk, the response time of the input / output (IO, input / output) of the hard disk will become longer and become a slow disk. In the storage system, user data can be stored in a series of hard disks. If a hard disk is slow, the overall read and write operations will slow down, and in severe cases, business interruption will occur. Therefore, it is necessary to detect each disk in the storage system in real time to determine the slow disk, so as to isolate or back up the slow disk in time. [0003] The existing slow disk detection method only compares the IO response time of the entire hard disk with the slow disk event judgment threshold to determine the slow disk event, and when the number of slow disk ev...
