Abstract: When managing stripes in a storage system, based on a determination that a failed storage device appears in first storage devices, a failed stripe involving the failed storage device is determined in a first redundant array of independent disks (RAID). An idle space that can be used to reconstruct the failed stripe is determined in the first storage devices. The failed stripe is reconstructed to second storage devices in the storage system based on a determination that the idle space is insufficient to reconstruct the failed stripe, the second storage devices being storage devices in a second RAID. An extent in the failed stripe is released in the first storage devices. Accordingly, it is possible to reconstruct a failed stripe as soon as possible to avoid data loss, and further to provide more idle spaces in the first storage devices for future reconstruction.
