Я использую следующее:
[root@kpdbm01 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)
[root@kpdbm01 ~]# uname -a

Я пытаюсь использовать clusvcadm к Disable/Enable/Relocate <group> но независимо от того, что я в итоге Failure.
Я вижу много сообщений, например, одно ниже внутри /var/log/cluster/corosync.log:

Чтобы обойти проблемы со связью, измените связь кластера с многоадресной рассылки по умолчанию на одноадресную:
< <cman expected_votes="1" two_node="1"/>
---
> <cman expected_votes="1" two_node="1" transport="udpu"/>
