Abstract
Apparatus and method for adding a storage device to a storage array without requiring a time-consuming reorganization of the data blocks and parity blocks in the original array. At least initially, new data blocks are only placed on the added storage device. The parity blocks that protect these new data blocks at least initially remain at their original locations on the original storage device and are not placed on the new storage device. To avoid having to recalculate the parity blocks after the new storage device is added, the data blocks in the new storage device may be initialized to zeros.
