I thought I had done this before, but this time it worked.  This still
leaves open the question of why split brain keeps occuring?  The
cluster is managed by pacemaker, version 1.1.6, with corosync, version
1.4.2.  There isn't actually any real data on the two drbd devices,
since this is only a test.  But it concerns me that it seems to go
into split brain about once a week.

We are moving to a new setup using independent networks with bonding,
which may prove more reliable.  Until now, the hardware for this has
not been available; that is, the networks exist, but I have had no
access to them.
