I'm using following:

[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
corosync-1.4.1-17.el6_5.1.x86_64
ricci-0.16.2-69.el6_5.1.x86_64
[root@kpdbm01 ~]#

I'm trying to use clusvcadm to Disable/Enable/Relocate <group> yet no matter what I end up with Failure.

I'm seeing a lot of messages such as one bellow inside of /var/log/cluster/corosync.log:

Aug 27 19:14:57 corosync [TOTEM ] Retransmit List: 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50 51 52 53 54 55

here is output from /var/log/cluster/rgmanager.log while I'm trying to Disable PR_MYSQL1:

As work around the communication difficulties, changing cluster communication from the default Multicast to Unicast:

<   <cman expected_votes="1" two_node="1"/>
---
>   <cman expected_votes="1" two_node="1" transport="udpu"/>
