I've done this on several occasions.
If you want to play with various scenarios in LVM, I'd recommend
reading the LVM How-To @ http://tldp.org/HOWTO/LVM-HOWTO/ . Sections
11 & 13 cover the most common tasks you'll encounter in LVM. Play
around, don't be afraid to break things, and if you have questions
feel free to give the list a shout.
