A computer storage system is described. A range of volume block numbers (VBNs) is assigned to a volume. A range of storage device block numbers (DBNs) is assigned to each of a plurality of storage devices. A first mapping parameters are created to map a first range of VBN numbers to a first selected range of DBNs using a first portion of a new storage device.
