ABSTRACT:
In one embodiment, a first storage device and a second storage device form a mirror. When the first storage device loses synchronization with the second storage device, data present in the second storage device but not in the first storage device are identified. The identified data are then copied to the first storage device. In one embodiment, a method of rebuilding data in a storage device includes the act of replacing a failed storage device with a replacement storage device. Up-to-date data for the failed storage device, which may be stored in a corresponding mirror, may then be copied to the replacement storage device. Thereafter, the replacement storage device and any other storage devices that have lost synchronization with their mirror are resynchronized.
