In {HEAD ~ light} of the original parameters for the logical data volume 174, the volume creation software 130 determines that the logical data volume 174 can be reallocated as logical data volume 176, which takes up {TAIL ~ less storage space} on the storage arrays 114, 116 and 118, but is spread to the additional storage array 120
