Abstract
Techniques for managing disks involve determining, based on a parameter related to a capability of a plurality of disks, a reference capability parameter for each of the plurality of disks. In addition, the techniques involve determining a used capability parameter for each of the plurality of disks. Moreover, the techniques involve determining from the plurality of disks a first disk to be adjusted, a used capability parameter of the first disk exceeds a reference capability parameter of the first disk. The techniques further involve causing data of at least one disk slice in the first disk to be moved to a second disk of the plurality of disks, such that a difference between the used capability parameter of the first disk and reference capability parameter of the first disk is below a predetermined threshold. Accordingly, a balanced operation among respective storage disks can be achieved.
