One thing that worries me is how difficult it makes it if you get some data corruption. For example, I had a hardrive that had full disk encryption start to fail, and found pulling the data off much more difficult because I had to decrypt the whole lvm to get any access. I'm actually not confident how exactly corruption maps from cyphertext to plaintext in various modern crypto systems. I would guess that you would get out gibberish though.
