Reducing Swap on an LVM2 Logical Volume
To reduce an LVM2 swap logical volume (assuming /dev/VolGroup00/LogVol01 is the volume you want to reduce):
- Disable swapping for the associated logical volume:
swapoff -v /dev/VolGroup00/LogVol01
- Reduce the LVM2 logical volume by 512 MB:
lvm lvreduce /dev/VolGroup00/LogVol01 -L -512M - Format the new swap space:
mkswap /dev/VolGroup00/LogVol01 - Enable the extended logical volume:
swapon -va - Test that the logical volume has been reduced properly:
cat /proc/swapsfree
