Abstract

The invention provides a disk data detection method and device. The method includes the steps of conducting read-write detection on data of a detection area reserved in a target disk; if an error is detected in the disk, according to the type of the error, processing the target disk. The disk data detection method and device can prevent disk service IO resources from being occupied by disk data IOverification, and the disk service IO performance is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a disk data detection method and device. Background technique [0002] Disk reliability refers to a feature in the storage system that regularly checks the correctness and integrity of data on the disk, and restores data when a disk failure is found to ensure high availability of the storage system. Disk reliability can be divided into two parts: disk failure detection and disk failure recovery. Disk failure detection can detect failures early, prevent users from making mistakes when using data, and improve data availability. Disk failure recovery is a method of recovering damaged data through other backup data after a failure is found on the disk. [0003] At present, the commonly used disk reliability scheme is usually to directly perform full-copy read verification on user data, and use multi-copy data comparison to check whether the user data is correct.
