I'm looking for a way to get MD to operate in a mode in which reading a sector from a RAID-1 device would not succeed until it got matching data from at least two components. Recent experience[1] suggests that a transient problem in one disk can completely hose a four way RAID-1 array, which is otherwise supposed to still be fine after a triple total failure. I'm hoping that a paranoid mode would have prevented that. If there is such a thing, PLEASE tell me. If not, please tell me so I don't waste any more time looking for it.
