Title:
DATA RECOVERY METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/108930
Kind Code:
A1
Abstract:
The present application discloses a data recovery method, in which each block in a stripe is divided into a plurality of elements on the basis of spatial distribution in a redundant array of independent disks, so that all elements in a P verification block and a Q verification block are generated on the basis of elements in data blocks. As a result, when two faulty disks requiring data recovery are present in the redundant array of independent disks, a verification formula can be established by combining the data blocks and the P verification block, and a verification formula can be established by combining the data blocks and the Q verification block, so that original data in the faulty disks is obtained by solving according to the two verification formulas, thereby achieving data recovery of the faulty disks in the redundant array of independent disks. Obviously, such a means of implementation does not need to be combined with other algorithms, and the implementation process thereof is simple, effectively improving the data recovery efficiency of faulty redundant arrays of independent disks. The present application further discloses a data recovery apparatus, a data storage method and apparatus in a redundant array of independent disks, a redundant array of independent disks, an electronic device, and a nonvolatile computer-readable storage medium, all of which have the aforementioned beneficial effects.
