I don't think you need to use dmsetup in your case, but can you post
*all* the commands you ran before you got to this point, and the
output of
cat /proc/mdstat
as well? Thinking on this some more, you might need to actually also
add:
--assume-clean
to the 'mdadm create ....' string, since you don't want it to zero the
array or anything.
Sorry for not remembering this at the time!
So if you can, please just start over from scratch, showing the setup
of the loop devices, the overlayfs setup, and the building the RAID6
array, along with the cat /proc/mdstat after you do the initial build.

now. Only citing with > now. :-)
