Abstract
A method, computer program product, and computer system for initializing, on a computing device, an N*N Weighted Neighborhood Matrix according to an existing Mapped RAID layout. N disks in an original disk partner group (DPG) may be partitioned into a target DPG, where N is a number of disks in an extent pool, wherein the N disks have at least two different capacities. The target DPG may be marked for at least a portion of the N disks. The target DPG may be marked for E RAID extents, where E is a number of RAID extents in the original DPG. At least a portion of disk extents for the E RAID extents in the original DPG may be moved to the target DPG.
