Abstract
An approach for efficiently managing logical volumes of data includes subdividing logical volumes of data into relatively small pieces that are spread over several physical disks. When a determination is made that a particular disk drive is to store more than one piece of a volume, a plurality of pieces of the volume are selected to be stored on the particular disk drive based at least in part on how far apart the pieces are within an address space of the volume. In response to an addition of one or more new drives to a system that contains a plurality of disk drives, at least a piece of each of the plurality of volumes may be moved from a drive of the plurality of disk drives to at least one of the one or more new drives.
