Abstract
Techniques for rebuilding a disk array involve, in response to receiving a message for rebuilding disk arrays in a storage system, determining a target disk that causes rebuilding. Such techniques further involve determining from the disk arrays a set of disk arrays related to the target disk, and generating subsets of disk arrays from the set of disk arrays, each subset including disk arrays that can be rebuilt in parallel. Such techniques further involve determining, based on a number of disks included in each subset, a target subset from the plurality of subsets, and rebuilding disk arrays in the target subset in parallel. Accordingly, a disk array that is most suitable for parallel rebuilding may be determined, and the process of rebuilding the disk array is sped up. Such techniques reduce the delay caused by performing rebuilding, and improve rebuilding efficiency.
