Creating an LVM2 Logical Volume for Swap

In our example we assume /dev/VolGroup00/LogVol02 is the swap volume you
want to add. To add a swap volume group please
1. Create the LVM2 logical volume of size 256 MB:
  • # lvm lvcreate VolGroup00 -n LogVol02 -L 256M
2. Format the new swap space:
  • # mkswap /dev/VolGroup00/LogVol02
3. Add the following entry to the /etc/fstab file:
  • /dev/VolGroup00/LogVol02 swap swap defaults 0 0
4. Enable the extended logical volume:
  • # swapon –va
5. Test that the logical volume has been extended properly:
  • # cat /proc/swaps # free
