Techniques for managing disks involve: determining, from multiple disks, a first disk set for providing redundant storage, the number of disks included in the first disk set being not less than a first threshold number that corresponds to the number of disks required to be included in a redundant array of independent disks; determining, based on the multiple disks, a candidate solution in which at least the first disk set is used to provide redundant storage; determining an unavailable capacity that the candidate solution will have; and determining, based on the unavailable capacity and the candidate solution, a target solution for providing the redundant storage. Accordingly, such techniques can promote efficient management of disks.
