Abstract
A technique performs Redundant Array of Independent Disks (RAID) transformation. The technique involves performing a garbage collection operation on a first uber within a storage array, the garbage collection operation freeing a set of disk slices of the first uber. The technique further involves, upon completing the garbage collection operation, reallocating storage of the set of disk slices from the first uber to a second uber within the storage array. The technique further involves, after the storage of the set of disk slices is reallocated from the first uber to the second uber, storing data within the second uber. Such leveraging of garbage collection when performing RAID transformation reduces overhead and wear without not negatively affecting system performance.
