I see why that would solve the problem.  However, I am concerned that it
might be overkill.  Most notably, I am concerned about adding an extra layer
of management and overhead.  Is there really no other way to manage the
association between physical volumes and DRBD volumes?  What about
configuring the drives by ID or by UUID (e.g.  /dev/disks/by-id/*)?

I am particularly interested in the fact that there seems to be little to no
information about this on the Internet.  This leads me to believe that there
is already a simple method in place to prevent this problem that I am
missing or that this is not actually a problem at all.
