.2.1. Extending Swap on an LVM2 Logical Volume To extend an LVM2 swap logical volume (assuming /dev/VolGroup00/LogVol01 is the volume you want to extend):
Disable swapping for the associated logical volume:
swapoff -v /dev/VolGroup00/LogVol01
Resize the LVM2 logical volume by 256 MB:
lvm lvresize /dev/VolGroup00/LogVol01 -L +256M
Format the new swap space:
mkswap /dev/VolGroup00/LogVol01
Enable the extended logical volume:
swapon -va
Test that the logical volume has been extended properly:
cat /proc/swaps
