配置cluster,手动开启的服务被cluster停止

Question

各位，在虚拟机上做cluster的测试，资源和服务列表（cluster.conf）如下：

[root@qt-esa-rh5 ~]# more /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="18" name="mycluster">

                        </fence>
                </clusternode>
                <clusternode name="QT-ESA-rh5.4-B" nodeid="2" votes="1">

                        </ip>
                </service>
        </rm>
</cluster>
[root@qt-esa-rh5 ~]#

配置好后，在主节点（192.168.122.11）上手动开启nfs和postgresql服务，然后开启cluster服务（cman,rgmanager），结果cluster却将在主节点上手动开启的postgesql服务关闭了，/var/log/messages信息如下：

好像是说从网关上收到了什么无效的包，从而引起服务关闭。请各位大大给指点一下。

Answer 1

如果你使用rgmanager，就不要手动启服务。rgmanager启动的时候会先stop服务，然后再start

Answer 2

另外，你可以使用fence_xvm代替manual fence。

Answer 3

能详细介绍一下fencd_xvm是什么东东吗？对这个东西不太熟悉，谢谢,另：现在测试过程中出现新的提示如下：
