配置cluster,手動開啟的服務被cluster停止
各位，在虛擬機上做cluster的測試，資源和服務列表（cluster.conf）如下：
# more /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="18" name="mycluster">
<fence_daemon post_fail_delay="0" post_join_delay="3"/>
<clusternodes>

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

</resources>

</netfs>
</ip>
</service>
</rm>
</cluster>

配置好后，在主節點（192.168.122.11）上手動開啟nfs和postgresql服務，然後開啟cluster服務（cman,rgmanager），結果cluster卻將在主節點上手動開啟的postgesql服務關閉了，/var/log/messages信息如下：

好像是說從網關上收到了什麼無效的包，從而引起服務關閉。請各位大大給指點一下。
《解決方案》
如果你使用rgmanager，就不要手動啟服務。rgmanager啟動的時候會先stop服務，然後再start
《解決方案》
另外，你可以使用fence_xvm代替manual fence。
《解決方案》
能詳細介紹一下fencd_xvm是什麼東東嗎？對這個東西不太熟悉，謝謝,另：現在測試過程中出現新的提示如下：
