[ClusterLabs] pacemaker remote configuration on ubuntu 14.04

[Сергей Филатов]

Thanks for an answer. Turned out the problem was not in ipv6.
Remote node is listening on 3121 port and it’s name is resolving fine.
Got authkey file at /etc/pacemaker on both remote and cluster nodes.
What can I check in addition? Is there any walkthrough for ubuntu?
