5.2.1. Extending Swap on an LVM2 Logical Volume

To extend an LVM2 swap logical volume (assuming /dev/VolGroup00/LogVol01 is the volume you want to extend):

  1. Disable swapping for the associated logical volume:

    # swapoff -v /dev/VolGroup00/LogVol01
    
  2. Resize the LVM2 logical volume by 256 MB:

    # lvm lvresize /dev/VolGroup00/LogVol01 -L +256M
    
  3. Format the new swap space:

    # mkswap /dev/VolGroup00/LogVol01
    
  4. Enable the extended logical volume:

    # swapon -va
    
  5. Test that the logical volume has been extended properly:

    # cat /proc/swaps # free
