Quick rebuild
Quick rebuild is a method for reconstructing virtual disk groups that reduces the time that user data is less than fully fault- tolerant after a disk failure in a disk group. Taking advantage of virtual storage knowledge of where user data is written, quick rebuild first rebuilds the data stripes that contain user data.
Typically, storage is only partially allocated to volumes so the quick-rebuild process completes significantly faster than a standard rebuild. Data stripes that have not been allocated to user data are reconstructed in the background, using a lightweight process that allows future data allocations to be more efficient
Quick rebuild applies to all RAID levels, including ADAPT. For an ADAPT disk group, depending on how much space is actually allocated, quick rebuild can be faster than RAID rebuild
Within a few minutes after a quick rebuild completes, a scrub starts on the disk group. For more information about disk-group reconstruction, see Reconstruction.
