Abstract
A plurality of stripe zones are mapped across drives in an array. A capacity of each of the stripe zones is smaller than or equal to an average size of the drives. A failed drive is determined in the array. A deletable stripe zone is selected that is being used for user data storage. The deletable stripe zone is taken offline and used to rebuild a subset of the plurality of the stripe zones affected by the failed drive.
