Hi! If I understand correctly, one cannot safely switch between 1.x metdata layouts since data offsets would be different, right? Why not to overcome this limitation by holding all three metadata zones reserved to prevent RAID data allocation inside them? It doesn't seem to be significant waste of disk space, but would be more flexible indeed. -- -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
