  1. Disable swapping for the associated logical volume:
    # swapoff -v /dev/VolGroup00/LogVol01
    
  2. Reduce the LVM2 logical volume by 512 MB:
    # lvm lvreduce /dev/VolGroup00/LogVol01 -L -512M
    
  3. Format the new swap space:
    # mkswap /dev/VolGroup00/LogVol01
    
  4. Enable the extended logical volume:
    # swapon -va
    
  5. Test that the logical volume has been reduced properly:
    # cat /proc/swaps # free
