7.3.2. 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 the Red Hat Enterprise Linux Installation Guide for instructions on booting into rescue mode. When prompted to mount the file system, select .
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 - Remove the LVM2 logical volume of size 512 MB:
lvm lvremove /dev/VolGroup00/LogVol02 - Remove the following entry from the
/etc/fstabfile:/dev/VolGroup00/LogVol02 swap swap defaults 0 0
- Test that the logical volume has been removed:
cat /proc/swapsfree
