just out of curiousity: how does xfs interact with things like

If your journal does not get out to disk and the data does not get out to
disk and the fs is not touched it would remain consistent.
If the journal gets written and the data does not or vice versa you can
probably imagine what happens.
The question is if both the journal and data end up in the same layer and
thus get written at the same time. I think that journal does not travel to
disk in the same path that the data does.
However this is a bit og guessing, let the brighter people answer this one.
Every program has two purposes one for which
it was written and another for which it wasn't
I use the last kind.
