Removing an LVM2 Logical Volume for Swap

The swap logical volume cannot be in use (no system locks or processes on the
volume). The easiest way to achieve this is to boot your system in rescue mode.
Refer to for instructions on booting into rescue mode. When prompted to mount
the file system, select Skip.
To remove a swap volume group
(Assuming /dev/VolGroup00/LogVol02) is the swap volume you want to remove:

1. Disable swapping for the associated logical volume:
  • # swapoff -v /dev/VolGroup00/LogVol02
2. Remove the LVM2 logical volume of size 512 MB:
  • # lvm lvremove /dev/VolGroup00/LogVol02
3. Remove the following entry from the /etc/fstab file:
  • /dev/VolGroup00/LogVol02 swap swap defaults 0 0
4. Test that the logical volume has been extended properly:
  • # cat /proc/swaps # free
