Extending Swap on an LVM2 Logical Volume

In our example we assume /dev/VolGroup00/LogVol01 is the volume you want
to extend. To extend an LVM2 swap logical volume please

1. Disable the swapping for the associated logical volume:
  • # swapoff -v /dev/VolGroup00/LogVol01
2. Resize the LVM2 logical volume by 256 MB:
  • # lvm lvresize /dev/VolGroup00/LogVol01 -L +256M
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 extended properly:
  • # cat /proc/swaps # free
