Another side effect of snapshots and using LVM for example(applies to any vendor's block based snapshots), is you can't easily take a snapshot of an LVM-based file system, then mount that snapshot on the same system, LVM will bitch.
if you have a SAN that supports logical volumes that have snapshot and grow and such, I'm not sure why you'd bother with LVM on top of that, it would just further obfuscate things.
