How to Create 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
