Embodiment Construction

[0124] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0125] Usually, a storage system is provided with multiple hard disks, and the performance of the multiple hard disks jointly affects the performance of the storage system. For example, the input and output response times of the multiple hard disks jointly affect the input and output response time of the storage system. The impact can be expressed as: when the input and output response time of one or several hard disks in the storage system increases relative to the respective rated input and output response time, it will slow down the input and output response speed of the entire storage system. In this way, the efficiency of the host in processing services will be affected, and in severe cases, the host services will be interrupted. The...

Abstract

The present application discloses a slow disk detection method and device, and a storage medium, which belong to the technical field of storage. The method includes: acquiring multiple eigenvalue groups obtained by detecting multiple tested hard disks, each eigenvalue group including at least one eigenvalue, and the at least one eigenvalue is used to reflect the multiple tested hard disks based on the multiple feature value groups, using the target anomaly detection algorithm to perform anomaly detection on the multiple tested hard disks; based on the first slow disk threshold and the result of the abnormality detection, determine the multiple The slow disk in the hard disk is measured, and the first slow disk threshold is determined according to a preset test sample library. The present application improves the accuracy of detecting slow discs. The present application is used to detect slow disks in storage systems.

Description

technical field [0001] The present application relates to the field of storage technology, and in particular, to a slow disk detection method and device, and a storage medium. Background technique [0002] During the use of the hard disk, due to the magnetic degradation, bad sectors or vibration of the hard disk, the response time of the hard disk when performing input / output (English: input / output, abbreviation: I / O) operations is relative to the rated I / O response. The time will increase, and the hard disk whose response time increases when performing I / O operations is called a slow disk. When there are slow disks in the storage system, the read and write operations of the entire storage system will slow down, which will affect the business processing efficiency of the host. In severe cases, it will lead to interruption of host business. Therefore, real-time detection of the hard disks in the storage system, and taking relevant measures such as isolation or backup for the...
