I cannot quite understand your problem.  As every part of the array
contains it's own metadata, it doesn't matter to md which /dev/sdX a
drive is.  It might matter a bit for boot-time assembly, but actually
that's what UUIDs are for.

But I understand yours, Michael.  You would like to put those
RAID0-pieces of your RAID10 each on a single controller.  I believe one
must find out what "NEAR" and "FAR" is.
I'd understand it as: "NEAR" is the closer disk - yeah.  Closer in the
array-tree, or it's logical base-LBA is closer?  Neil, could you please
clarify which is which?
