摘要
Techniques rebuild data in a storage array group. Such techniques involve: in response to determining that a first storage device of a plurality of storage devices comprised in the storage array group is in a non-working state, generating a write record of the first storage device, the write record indicating whether a write operation occurs for each of a plurality of storage areas in the first storage device during the non-working state; in response to determining that the first storage device returns from the non-working state to a working state, determining, based on the write record, whether a target storage area in need of execution of data rebuilding is present in the first storage device; and controlling, based on the determining, the data rebuilding to be executed on the target storage area.
