Hello, Andrew.
You are a little misunderstood me.
I wrote that I rushed to judgment.
After I did the reverse DNS zone, the cluster behaved correctly.
BUT after I took apart the cluster dropped configs and restarted on the new cluster,
cluster again don't showed all the nodes in the nodes (only node with running pacemaker).
A small portion of the log. Full log
In which (I thought) there is something interesting.
