Abstract
Storage devices in a pool are divided into at least one group with a first number of storage devices in an existing group not higher than a range. When a second number of storage devices are added to the resource pool, a sum of the first number and the second number is determined. A new group is created based on at least a portion of the second number of storage devices when the sum does not satisfy the range; and another portion of the second number of storage devices are added to the existing group. A first storage space portion in each of a set of shared storage devices selected from the existing group is allocated to the existing group, and a second storage space portion in each of the set of shared storage devices is allocated to the new group. The storage space utilization rate can be increased.
