11.2.2. Creating an LVM2 Logical Volume for Swap

To add a swap volume group (assuming /dev/VolGroup00/LogVol02 is the swap volume you want to add):
  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
