redhat群集故障转移不起作用(cor产c [TOTEM ]重传列表)

Question

我用的是：

[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 ~]# 

我正在尝试使用Disable/Enable/Relocate <group>使用clusvcadm，但不管我最终得到的是Failure。

我看到了很多信息，比如/var/log/cluster/corosync.log里面的一个低端消息：

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 

下面是/var/log/cluster/rgmanager.log在尝试Disable PR_MYSQL1时的输出：

下面是clustat的输出：

[root@kpdbm02 ~]# 

有什么好主意吗？我该怎么处理呢？

为了解决通信困难，将集群通信从默认的多播更改为Unicast：

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