Except for a crash at the precise moment that data is being written during a resize of a partition in LVM or the filesystem iteself. To my knowledge, said operation is not journaled.
WTF is the doc for this? wth do I have an incomplete Documentation/ tree or something? I dunno, maybe I read about LVM on some site or something. It doesn't matter; it's been too many years since I've though about it or read about it or even seen it.
