摘要:
Exemplary embodiments of the present invention comprise a method for the use of an intra-disk redundancy storage protection operation for the scrubbing of a disk. The method comprises initiating a disk scrubbing operation upon each disk of a plurality of disks that are comprised within a storage disk array, issuing a disk scrubbing command for a predetermined segment of the disks that are comprised within the storage disk array at a predetermined time interval, and identifying an unrecoverable segment on a disk. The method further comprises determining if unrecoverable sectors comprised within the unrecoverable segment can be reconstructed, and reconstructing the unrecoverable sectors of the unrecoverable segment and relocating the segment to a spare storage location on the disk in the event that the segment cannot be reconstructed within its original storage location.
