ABSTRACT:
Various embodiments for rapid defragmentation of storage volumes in a computing environment are provided. A plurality of source data sets is copied from the fragmented storage volume to a plurality of target data sets on an additional storage volume. The plurality of source data sets is placed on the additional storage volume as the plurality of target data sets in an unfragmented order. A first volume serial number (VOLSER) of the fragmented storage volume is swapped with a second VOLSER of the additional storage volume. The fragmented storage volume is varied offline, and the additional storage volume is varied online. The computing environment recognizes the additional storage volume having the plurality of target data sets placed in the unfragmented order.
