You can hot add space to a lv, but not take space away from a lv. So if
you have spare room on the disk, then you can just lvextend then
resize2fs (assuming ext3).
If you have no spare room on the disk, you will need to boot into say,
single user mode, umount some lv (say /home) and resize the fs smaller,
then lvresize smaller. You can now add the unused extends to the small
root: lvextend -l SOMEEXTENDSNUMBER /dev/VGName/LVName
resize2fs /dev/VGName/LVName
