Abstract

Techniques perform storage management. The techniques involve: in response to a target request for a target redundant array of independent disks (RAID), determining that data in a first storage block associated with the target RAID needs to be moved or copied, wherein the target request includes one of the following: a restriping request, a type conversion request, or a rebalancing request; creating an intermediate RAID associated with an idle 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 this mode, RAID restriping, type conversion, or rebalancing can be implemented efficiently.
