A system for policy-driven RAID rebuild includes an interface to a group of devices each having stripe units. At least one of the devices is a spare device available to be used in the event of a failure of a device in the group of devices. The system further includes a processor coupled to the interface and configured to determine, based at least in part on an ordering criteria, an order in which to reconstruct stripe units to rebuild a failed device in the group of devices. The processor is further configured to rebuild the failed device including by reconstructing stripe units in the determined order using the spare device to overwrite stripe units as needed.

Policy-driven raid rebuild

Efficient use of spare device(s) associated with a group of devices is disclosed, including: receiving a set of data; storing the set of data across a group of devices according to a protocol; determining a set of additional data units associated with the set of data; and storing the set of additional data units in a spare device associated with the group of devices, wherein the spare device is available to be used in the event of a failure of a device included in the group of devices, including by overwriting the set of additional data units as needed.
