Abstract
Techniques for extending a storage system having a first pool involve adding, in response to a request, second storage devices, wherein the first pool is generated using first storage devices and based on a first standard. The first pool includes first stripes created using the first standard, and the number of the second storage devices equals a first stripe width associated with the first standard. Such techniques further involve creating a second pool using the second storage devices and based on a second standard, wherein a second stripe width associated with the second standard equals the first stripe width. Such techniques further involve creating second stripes in the second pool using the second storage devices and based on the second standard. Such techniques further involve storing data of at least one of the first stripes to a corresponding stripe of the second stripes according to a data shuffle rule.
