兩台虛擬機做RHCS集群出錯
架構： 虛擬機A 在physical-A 上， 虛擬機B在physical-B上。
想為A和B 做一個集群 。 不知道兩台虛擬機做集群是否可行。
B為A的失效域中成員。
A和B的配置文件為：
<?xml version="1.0"?>
<cluster alias="apache-cluster" config_version="5" name="apache-cluster">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="physical2-virt1.sys.com" nodeid="1" votes="1">
<fence/>
</clusternode>
<clusternode name="physical1-virt1.sys.com" nodeid="2" votes="1">
<fence/>
</clusternode>
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<fencedevices/>
<rm>
<failoverdomains>
<failoverdomain name="prefer_physical1-virt1" nofailback="0" ordered="1" restricted="0">
<failoverdomainnode name="physical2-virt1.sys.com" priority="10"/>
<failoverdomainnode name="physical1-virt1.sys.com" priority="1"/>
</failoverdomain>
</failoverdomains>
<resources>
<ip address="192.168.1.210" monitor_link="1"/>
<script file="/etc/rc.d/init.d/httpd" name="web"/>
</resources>
<service autostart="1" domain="prefer_physical1-virt1" exclusive="0" name="apache" recovery="relocate">
<ip ref="192.168.1.210">
<script ref="web"/>
</ip>
</service>
</rm>
</cluster>
配置完后，當重啟A機器后，B機器可以正常的接管A上面的服務，
可是當A重啟卻起不來cman服務：
Starting cluster:
Loading modules... DLM (built Apr 29 2008 13:46:34) installed
GFS2 Overlay (built Apr 30 2008 17:30:59) installed
done
Mounting configfs... done
Starting ccsd... done
Starting cman... failed
Timed-out waiting for cluster
從而無法在啟動后或者B失效後接替服務。

《解決方案》
看到jerrywjl在別的地方會的貼，知道是哪裡出錯了。嘿嘿
謝謝jerrywjl 了
是我的機器的防火牆忘記關閉了。
這個錯誤很簡單，可是也很容易犯。

這哥們滿世界貼。。。。。。
