Abstract
Techniques involve: determining, according to a received request for creating a stripe in a storage system, a type of the stripe; acquiring a first workload distribution corresponding to the determined type, wherein the first workload distribution describes the distribution, among a first number of storage devices, of multiple extents in a set of stripes of this type in the storage system; selecting a set of extents from the first number of storage devices based on the first workload distribution, so that the distribution, among the first number of storage devices, of the selected set of extents and the multiple extents in the set of stripes of this type satisfies a preset distribution condition associated with the type; and using the selected set of extents to create the requested stripe based on a stripe creation rule associated with the type. The stripes can be managed in a more effective manner.
