redhat 集群故障转移不起作用（corosync [TOTEM] 重新传输列表）

我正在使用以下内容：

[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 ~]#

我尝试使用clusvcadm/ Disable/Enable但Relocate <group>无论我最终得到什么Failure。

我看到很多消息，例如下面的消息/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

这是/var/log/cluster/rgmanager.log我尝试时的输出Disable PR_MYSQL1：

有什么想法出了什么问题吗？我该如何解决它？

答案1

为了解决通信困难，将集群通信从默认的多播更改为单播：

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