Abstract
Data is migrated. For instance, in response to detection of a failed group in a drive of groups comprising respective blocks, it is determined whether the total number of groups in the drive that have failed is less than a predetermined threshold. Data associated with the failed group is migrated to a reserved group in a reserved space of the drive according to a determination that the total number is less than the predetermined threshold; and a read/write (I/O) request to the failed group is redirected to the reserved group based on a mapping relationship from the failed group to the reserved group. Consequently, data does not need to be repaired on an entire drive due to one failed write request and replacing the drive is avoided, thereby saving resources, time and labor, and improving the impact of the failed write request on the performance of a storage system.
