Abstract

Embodiments of the invention provide a slow disk detection method and apparatus, which relates to the technical field of computers and can solve the problem of low slow disk detection precision. The method comprises the steps of obtaining average service time of input / output (I / O) requests corresponding to different types of hard disks in a current preset period; obtaining slow disk thresholds corresponding to the different types of hard disks in a next preset period according to a relationship between the average service time of the I / O requests corresponding to the different types of hard disks and a preset value; and determining slow disks in the next preset period according to the slow disk thresholds corresponding to the different types of hard disks and the average service time of the I / O requests corresponding to the hard disks in the next preset period. The method and the apparatus are used for dynamically adjusting the slow disk thresholds.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a slow disk detection method and device. Background technique [0002] The disk array system can include multiple redundant arrays of independent disks (Redundant Array of Independent Disks, RAID), which is a hard disk group (logical hard disk) formed by combining multiple independent hard disks (physical hard disks) in different ways. ). By placing data on multiple hard disks, input and output operations can overlap in a balanced manner, improving performance, thereby providing higher storage performance than a single hard disk and providing data backup technology. At the same time, when storing data, the data is cut into many sections and stored on each hard disk respectively. [0003] For the disk array system, when the hard disk aging, magnetic head degradation, hard disk bad sectors, etc. occur in the system, the response speed of the hard disk will slow down. T...
