11.2.1. 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
