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):

Create the LVM2 logical volume of size 256 MB:

 # lvm lvcreate VolGroup00 -n LogVol02 -L 256M

Format the new swap space:
```
 # mkswap /dev/VolGroup00/LogVol02 
```

Add the following entry to the /etc/fstab file:

 /dev/VolGroup00/LogVol02 swap swap defaults 0 0

Enable the extended logical volume:
```
 # swapon -va 
```
Test that the logical volume has been extended properly:
```
 # cat /proc/swaps # free 
```
