Abstract
Techniques manage a storage system. Along these lines, a failed storage device is detected among storage devices included in a resource pool of the storage system, and the storage devices belong to a first group and a second group in the resource pool respectively. An extent in the failed storage device assigned for building a stripe in the storage system is determined. A spare reserved extent is selected from respective reserved extents included in respective storage devices among the storage devices based on a mapping relation between the stripe and a plurality of extents in the stripe. The respective reserved extents are shared among the first group and the second group. Data in the extent are rebuilt to the selected spare reserved extent. A reserved storage area can be shared among various storage devices in the resource pool, so as to increase allocatable space in storage devices.
