Creating an LVM2 Logical Volume for Swap

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
