I've been using LVM on software raid 1 and raid 5 for some time now,
it's pretty easy to set up during the install, and once you've booted
you can use gui based LVM utilities like system-config-lvm to redraw
your volume sizes. Very convenient! What I usually do is create one
enormous logical volume, then multiple volume groups (for home, var,
whatever), and then save a bunch of space that you can allocate later
when you need to grow a filesystem. I'm using centos now, but I've also
done this on debian systems and it's surprisingly easy to do, although I
have to admit I haven't shrunken any filesystems- that still seems a bit
scary :-0
Cheers,
Scott VanDusen
