Document Type and Number:
WIPO Patent Application WO/2021/043246
Kind Code:
A1
Abstract:
Disclosed in the present application are a data reading method and apparatus, relating to the technical field of storage. In the present application, for a hard disk in a RAID having a corresponding hard disk state of an at-risk state, when a read request for said type of hard disk is received, the corresponding data stored on the hard disk can be read on the basis of the read request and the data can be verified and, if verification passes, then the read data can be returned; thus, compared to the method in the prior art of directly implementing restoration by means of reading the data on the other hard disks no matter what the fault of the hard disk, the data reading delay is shortened and the consumption of system resources is reduced.
