I wasn't complaining.  You know me better than that.

The cops caught me robbing a bank.  Under pressure, I pointed at you and

Agreed.  Which was the point I originally made in this thread.  "We"
simply got a minor detail wrong.  It seems folks on the linux-raid list

lost when the discussion drops into the weeds.

Sorry I dragged you into this Dave.
