Abstract
Techniques involve determining updated disk sets. The techniques further involve determining, from the updated disk sets, a target disk set for a storage unit associated with a plurality of storage disks. The techniques further involve determining position information of disk slices corresponding to the storage unit in the plurality of storage disks, in which the position information indicates respective updated disk sets in which the disk slices are located. The techniques further involve in accordance with a determination that an updated disk set indicated by position information of at least one of the disk slices is different from the target disk set, moving data in the at least one disk slice to the target disk set. Accordingly, an arrangement of a storage units across different disk sets can be avoided, and utilization rates of a plurality of storage disks can be made more uniform.
