Extend lvm swap volume

To extend an LVM2 swap logical volume

(assuming /dev/VolGroup00/LogVol01 is the volume you want to extend):

Disable swapping for the associated logical volume:
```
# swapoff -v /dev/VolGroup00/LogVol01
```

Resize the LVM2 logical volume by 256 MB:

# lvm lvresize /dev/VolGroup00/LogVol01 -L +256M

Format the new swap space:
```
# mkswap /dev/VolGroup00/LogVol01
```
Enable the extended logical volume:
```
# swapon -va
```
