Abstract
Techniques involve: determining a first group of storage disks, a use rate of each storage disk of the first group of storage disks exceeding a first threshold, the first group of storage disks comprising a first group of storage blocks corresponding to a first redundant array of independent storage disk (RAID); allocating a second group of storage blocks corresponding to a second RAID from a second group of storage disks, the second group of storage blocks having the same size as that of the first group of storage blocks, a use rate of each storage disk of the second group of storage disks being under a second threshold; moving data in the first group of storage blocks to the second group of storage blocks; and releasing the first group of storage blocks from the first group of storage disks. Thus, use rates of the storage disks become more balanced.
