11.3.2. Removing an LVM2 Logical Volume for Swap

To remove a swap volume group (assuming
/dev/VolGroup00/LogVol02 is the swap volume you want to remove):
- Disable swapping for the associated logical volume:
swapoff -v /dev/VolGroup00/LogVol02
# swapoff -v /dev/VolGroup00/LogVol02Copy to Clipboard Copied! Toggle word wrap Toggle overflow - Remove the LVM2 logical volume of size 512 MB:
lvm lvremove /dev/VolGroup00/LogVol02
# lvm lvremove /dev/VolGroup00/LogVol02Copy to Clipboard Copied! Toggle word wrap Toggle overflow - Remove the following entry from the
/etc/fstabfile:/dev/VolGroup00/LogVol02 swap swap defaults 0 0
