Both claims, it seems. I can't say for sure whenever write ordering is preserved by raid -- it should, and if it isn't, it's a bug and should be fixed. Nothing else is wrong with placing journal into raid (the same as the filesystem in question). Suggesting to remove journal just isn't fair: the journal is here for a reason. And, finally, the kernel should not crash. If something like this is unsupported, it should refuse to do so, instead of crashing randomly. /mjt
