Re: filesystem corruption with RAID6.

Note: the corruption Jim found and which I have confirmed are only
when doing large number of writes to a filesystem in degraded mode.
If you see something different, please let me know.  It would
definitely help tracking this down.

  ah!  that explains it then.  I was indeed copying over data in
  degraded mode.
   

The bug is elusive enough that it's difficult :-/

  ouch.  and RAID that can't be written to in degraded mode is
  somewhat impractical for production use.  ;-)
 
  is there anything I can do to help?  otherwise, I'll fall back to
  RAID5 and prepare the box for production.
