Abstract
The present disclosure discloses a method and a system for performing check recovery based on Gaussian elimination, a apparatus, and a storage medium. The method includes: a disk array by using normal data blocks and normal check blocks is constructed, a first reference matrix constructed by using coding matrix rows corresponding to the normal data blocks and the normal check blocks is converted into an inverse matrix through Gaussian elimination; it is determined that coding matrix rows corresponding to a predetermined quantity of blocks, and a second reference matrix is constructed by using the coding matrix rows, the abnormal data blocks, and the abnormal check blocks; and the inverse matrix and the second reference matrix are multiplied to obtain a first matrix, the first matrix and the disk array are multiplied to obtain an output matrix, and original data are obtained according to the output matrix.
