Optimized reconstruction and copyback methodology for a failed drive in the presence of a global hot spare disc |
摘要 |
The present invention is a system for optimizing the reconstruction and copyback of data contained on a failed disk in a multi-disk mass storage system. A system in accordance with the present invention may comprise the following: a processing unit requiring mass-storage; one or more disks configured as a RAID system; an associated global hot spare disk; and interconnections linking the processing unit, the RAID and the global hot spare disk. In a further aspect of the present invention, a method for the reconstruction and copyback of a failed disk volume utilizing a global hot spare disk is disclosed. The method includes: detecting the failure of a RAID component disk; reconstructing a portion of the data contained on the failed RAID component disk to a global hot spare disk; replacing the failed RAID component disk; reconstructing any data on the failed RAID disk not already reconstructed to the global hot spare disk to the replacement disk; and copying any reconstructed data from the global hot spare disk back to the replacement RAID component disk.
