7.3.2. Removing an LVM2 Logical Volume for Swap

Refer to the Red Hat Enterprise Linux Installation Guide for instructions on booting into rescue mode. When prompted to mount the file system, select .

/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
