Reducing Swap on an LVM2 Logical Volume

To reduce an LVM2 swap logical volume (assuming /dev/VolGroup00/LogVol01 is the volume you want to extend): Replace /dev/VolGroup00/LogVol01 with your HD partition. Disable swapping for the associated logical volume: # swapoff -v /dev/VolGroup00/LogVol01 Reduce the LVM2 logical volume by 512 MB: # lvm lvreduce /dev/VolGroup00/LogVol01 -L -512M Format the new swap space: # mkswap /dev/VolGroup00/LogVol01
