Abstract
A storage system includes stripes, extents included in one stripe among the stripes reside on storage devices in the storage system, respectively, and the storage system includes an address mapping between the stripe and storage devices where the extents reside. Regarding one extent, a storage device where the extent resides is determined among the storage devices based on the address mapping. The stripe is added to a rebuild list of the storage system in accordance with determining the storage device is a failed storage device, the rebuild list comprising a stripe that is to be rebuilt in the storage system. The storage system is rebuilt based on stripes in the rebuild list. Accordingly, the performance of a rebuild operation may be improved, and the time for the rebuild operation may be reduced. Further, there is provided a corresponding device and computer program product for managing a storage system.
