Abstract

The embodiment of the invention relates to a storage management method, device and a computer program product. The method comprises the steps that a first set of storage disks are determined from a plurality of storage disks, the utilization rate of each storage disk in the first set of storage disks is higher than a first threshold value, and the first set of storage disks comprise a first set of storage blocks corresponding to a first independent storage disk redundant array RAID; the method also includes distributing a second group of storage blocks corresponding to the second RAID from a second group of storage disks in the plurality of storage disks, the second group of storage blocks having the same size as the first group of storage blocks, and the utilization rate of each storage disk in the second group of storage disks being less than a second threshold; moving the data in the first group of storage blocks to a second group of storage blocks; and releasing the first set of memory blocks from the first set of memory disks. Therefore, the utilization rate of a plurality of storage disks can be more balanced.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computers, and more particularly, to methods, devices and computer program products for storage management. Background technique [0002] In a storage system based on a Redundant Array of Independent Disks (RAID), if a storage disk fails, the storage system can use data in other storage disks to restore data in the failed disk. However, when the storage disk group that constitutes the RAID changes (for example, adding or reducing disks), the usage rate of each storage disk may vary greatly, so that the IO conditions and wear conditions of each storage disk may be different, and the limit The storage space that can be provided to the user. Contents of the invention [0003] Embodiments of the present disclosure provide a solution for storage management. [0004] According to a first aspect of the present disclosure, a storage management method is proposed. The method includes: determining...
