I had XFS eat some data once. I somehow got it into a state where it wouldn't mount and wouldn't fsck. Luckily for me it was "just" my backup disk, so after a week of fighting with it I just gave up and reformatted (as ext4) and didn't end up losing much. Was eye opening though. I'd rather have a slightly less featureful fs that I have a chance of recovering…
