INTELLIGENT AND EFFICIENT RAID REBUILD TECHNIQUE

摘要

A method for servicing a redundant array of independent storage drives (i.e., RAID) includes performing a service call on the RAID by performing the following steps: (1) determining whether the RAID includes one or more consumed spare storage drives; (2) in the event the RAID includes one or more consumed spare storage drives, physically replacing the one or more consumed spare storage drive with one or more non-consumed spare storage drives; and (3) initiating a copy process that copies data from a storage drive that is predicted to fail to a non-consumed spare storage drive associated with the RAID. The service call may then be terminated. After the service call is terminated, the method waits for an indication that a number of non-consumed spare storage drives in the RAID has fallen below a selected threshold. A corresponding apparatus and computer program product are also disclosed.

1. A method for servicing a redundant array of independent storage drives (i.e., RAID), the RAID comprising a storage drive that is predicted to fail, the method comprising:
performing a service call on the RAID, wherein performing the service call comprises: (1) determining whether the RAID comprises at least one consumed spare storage drive; (2) in the event the RAID comprises at least one consumed spare storage drive, physically replacing the at least one consumed spare storage drive with at least one non-consumed spare storage drive; and (3) initiating a copy process that copies data from the storage drive that is predicted to fail to a non-consumed spare storage drive; terminating the service call; and after the service call has been terminated, waiting for an indication that a number of non-consumed spare storage drives in the RAID has fallen below a selected threshold.
