wrong in my understanding here: with LVM, I can keep adding more drives
to a 'pool' and expand the size of the 'volume' that the OS sees
available to it... but if any drive in that volume fails, I'd probably
lose everything stored in that volume?!? Sounds like a somewhat risky
business to me, unless you *really* needed a storage volume that big
that you had to span multiple drives to do so.
