For debugging, e.g. after fencing: is there something in the logs form where
i recognize which one was DC and which not ? E.g. some differences in the
pacemaker.log ?
What is about changes of the CIB and the following actions ? If after a diff in
the CIB pengine is doing s.th.,
this must be the DC i guess.
