Abstract

The embodiment of the invention relates to a storage management method, storage management equipment and a computer program product. The method comprises the steps that in response to a target request for a target RAID, it is determined that data in a first storage block associated with the target RAID needs to be moved or copied, and the target request comprises one of a re-striping request, a type conversion request or a re-balancing request; creating an intermediate RAID (Redundant Array of Independent Disks) associated with the free second storage block; and copying the data in the first storage block to a corresponding storage space in the intermediate RAID to write at least part of the data in the second storage block. Based on the mode, re-striping, type conversion or re-balancing of the RAID can be efficiently realized.

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 recent years, with the development of computer technology, people pay more and more attention to the security of data storage. Some traditional solutions use redundant array of independent disks (RAID) to improve the reliability of data storage. During the use of RAID, due to performance or reliability considerations, it is necessary to move data in some disks to another disk. Such data movement may involve the access of a large amount of RAID metadata, making it inefficient. 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: in response to a target request for...
