I'm really not sure. See the bugzilla above. The problem is that
at the time of 1.0.7 the CRM and the shell were out of sync on
the matter.

The doc on crm cli: http://www.clusterlabs.org/doc/crm_cli.html
but the resource sets are not described. I'll fix that tomorrow.

What you described above is order of operations:

order o1 inf: A:promote B:start ( C D E )

It should look like that. Anyway, you'll probably have to wait for
1.0.8. Or grab current sources.
