This ability alone makes it worth going to LVM. Never again do you need to move 
all of your data somewhere else when your partition fills up. All you need to do 
it throw another disk at it, and whammo- more space! That's how HP-UX does its 
filessystems by default and it make life so much easier.

Anyone know if it is possible to resize logical volumes on the fly in Linux?
