2个没有联机的cor产c节点(1个离线，1个在线)

Question

目前，我正试图根据本教程建立corosync：

http://www.howtoforge.com/how-to-set-up-an-active-passive-postgresql-cluster-with-pacemaker-corosync-and-drbd-centos-5.5-p3

但是，我无法连接我的两个节点。

我有两个节点：

data-master with IP address LAN: 10.0.0.122, Crossover: 172.16.0.1
data-slave with IP address LAN: 10.0.0.123, Crossover: 172.16.0.2

这是我的/etc/cor产c/cor产c.conf(与教程完全相同)：

兼容性:白兰地

totem {
   version: 2
   secauth: off
   threads: 0
   interface {
       ringnumber: 0
       bindnetaddr: 10.0.0.0
       mcastaddr: 226.94.1.1
       mcastport: 4000
   }
}

logging {
   fileline: off
   to_stderr: yes
   to_logfile: yes
   to_syslog: yes
   logfile: /tmp/corosync.log
   debug: off
   timestamp: on
   logger_subsys {
      subsys: AMF
      debug: off
   }
}

amf {
   mode: disabled
}
aisexec {
   user: root
   group: root
}
service {
   # Load the Pacemaker Cluster Resource Manager
   name: pacemaker
   ver: 0
}     

我能够成功地开始开放服务。但是，当我在两个节点上检查crm_mon -1时，它们的结果是不同的：

节点1(数据-主)

Last updated: Tue Feb 25 19:24:48 2014
Last change: Tue Feb 25 18:49:19 2014 by root via cibadmin on data-master
Stack: classic openais (with plugin)
Current DC: data-master - partition WITHOUT quorum
Version: 1.1.9-2db99f1
2 Nodes configured, 2 expected votes
0 Resources configured.


Online: [ data-master ]
OFFLINE: [ data-slave ]

节点2(数据-从)

Last updated: Tue Feb 25 19:25:10 2014
Last change: Tue Feb 25 18:47:17 2014 by root via cibadmin on data-master
Stack: classic openais (with plugin)
Current DC: data-slave - partition WITHOUT quorum
Version: 1.1.9-2db99f1
2 Nodes configured, 2 expected votes
0 Resources configured.


Online: [ data-slave ]
OFFLINE: [ data-master ]

我期望的是将两个节点连接在一起：

Online: [ data-master data-slave ]

你们能帮我找出我到底错过了什么吗？

我的平台: VirtualBox，两个节点都使用带有HA扩展的SLES 11 SP3，局域网的客户IP地址都是桥接的，交叉是内部网络模式。

谢谢!

可能您需要从多播通信切换到单播。

在您的corosync.conf中尝试这样的方法：

totem {
        version: 2
        secauth: off
        interface {
                member {
                        memberaddr: 172.16.0.1
                }
                member {
                        memberaddr: 172.16.0.2
                }
                ringnumber: 0
                bindnetaddr: 172.16.0.0
                mcastport: 5405
        }
        transport: udpu
}
