Abstract: Provided are a computer program product, system, and method for processing a space release command when mirroring data at a source storage to a target storage. A space release command is received to free a release space in the source storage while transferring changed data in a consistency group. A determination is made as to whether a transfer time to transfer remaining consistency group data in the consistency group for the release space that has not been transferred exceeds a response time to process a space release command. The remaining consistency group data in the release space is transferred to the target storage in response to determining that the transfer time does not exceed the response time. The release space for the space release command is freed in response to transferring the consistency group data in the release space to the target storage.

Abstract: A system and method reduces cleaning overhead in a storage array by establishing owner groups for selectively organizing memory page groups. The method generates a metadata lookup structure to correlate a disk address of the real-time data generated to a logical block address on the select storage volume.

The method selectively generates a memory snapshot of the current state of the select storage volume to form a subsequent owner group. Additionally, the method enables the first owner group and the subsequent owner group to reference the logical block address that is associated with the memory page group until a real-time data write provides a new logical block address that is associated with a new memory page group.
