A method and system is disclosed for providing defragmentation of extremely large volumes such that those data sets that were allocated in physical extent units would not have to be actually moved. The method and system disclosed herein modifies the hardware mapping of the physical extents to logical cylinder address on the host system to make it appear that the blocks had actually been moved, without actually moving the blocks.
