Well, if all you change is the version number then that's all that will
change in cman. In fact it will only change then if you tell it using
cman_tool, or bring a new node into the cluster using that file version
number, so I don't see anything wrong with the behaviour you're seeing.
I don't know how rgmanager gets to know about a new file.
