[Pacemaker] Master/Slave Resource and Stop/Start of HA System

[Eliot Gable]

Bug 2162 has been opened for this:

http://developerbugs.linux-foundation.org/show_bug.cgi?id=2162

Let me know if you need any additional information. I assume you should be able to reproduce it on your own with any master/slave resource. If not, then we can look at what's different with my setup from your test setup.
