Thank you again, Klaus.
Your description helps me to recognize a situation better (i've 
overworked a bit and can't this this not so nontrivial think by myself =)).

[
I've a scenario in the mind when an ability to mark a corosync ring as 
failed would be useful, but It doesn't relate to this topic.
It implemention on a corosync side would require some additional 
functionality for "checking" (let's call them so) rings that can be used 
only for network checking (not for cluster data synchronization). And 
the brokage of all "checking" rings (or some more enhanced logic) would 
indicate that the node is down or has the split brain. Just an idea.

No the ability? Ok, i try to deal with it )
