How to Create an LVM2 Logical Volume for Swap

Posted on 4:30 PM by Bharathvn

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
