Abstract
A method for reducing stress on a RAID under rebuild is disclosed herein. In one embodiment, such a method includes performing the following actions while the RAID is undergoing a rebuild process: (1) redirect writes intended for the RAID to a temporary storage area located on a same primary storage system as the RAID, and (2) redirect reads intended for the RAID to a secondary storage system configured to store a copy of data in the RAID. The method is further configured to perform the following actions upon completing the rebuild process: (3) update the rebuilt RAID to reflect writes made to the temporary storage area during the rebuild process, and (4) redirect reads and writes to the rebuilt RAID. A corresponding system and computer program product are also disclosed.
