Abstract
Methods and systems for efficient rebuild of storage devices in a RAID may include generating a data-modified map of a storage device. The data-modified map may be updated when a RAID virtual device associated with the storage device is degraded to indicate write operations. The data-modified map may be used to rebuild selective portions of the storage device, instead of performing a full rebuild. The data-modified map may also be used to perform a full rebuild of the storage device.
