Como funciona em torno das dificuldades de comunicação, alterando a comunicação do cluster do padrão Multicast para Unicast:
< <cman expected_votes="1" two_node="1"/>
---
> <cman expected_votes="1" two_node="1" transport="udpu"/>
Estou usando o seguinte:
[root@kpdbm01 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)
[root@kpdbm01 ~]# uname -a
Linux kpdbm01 2.6.32-431.20.3.el6.x86_64 #1 SMP Fri Jun 6 18:30:54 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux
[root@kpdbm01 ~]# rpm -q rgmanager cman corosync ricci
rgmanager-3.0.12.1-19.el6.x86_64
cman-3.0.12.1-59.el6_5.2.x86_64

ricci-0.16.2-69.el6_5.1.x86_64
[root@kpdbm01 ~]#
Estou tentando usar clusvcadm to Disable / Enable / Relocate <group> , não importa o que eu acabe com Failure .
Estou vendo muitas mensagens, como uma abaixo de /var/log/cluster/corosync.log :

aqui está a saída de /var/log/cluster/rgmanager.log enquanto eu estou tentando Disable PR_MYSQL1 :
