检查过程中是否有错误产生
[root@node1 corosync]# grep -i error: /var/log/messages |grep -v unpack_resources
查看pacemaker是否正常启动：
[root@node1 corosync]# grep -i pcmk_startup /var/log/messages
Oct 20 13:08:39 localhost corosync[32303]: [pcmk ] info: pcmk_startup: CRM: Initialized
Oct 20 13:08:39 localhost corosync[32303]: [pcmk ] Logging: Initialized pcmk_startup
Oct 20 13:08:39 localhost corosync[32303]: [pcmk ] info: pcmk_startup: Maximum core file size is: 4294967295
Oct 20 13:08:40 localhost corosync[32303]: [pcmk ] info: pcmk_startup: Service: 9
Oct 20 13:08:40 localhost corosync[32303]: [pcmk ] info: pcmk_startup: Local hostname: node1.a.com
将前面的验证步骤在另外一个节点上再次验证一次
在任何一个节点上 查看集群的成员状态
[root@node1 corosync]# crm status

Current DC: node1.a.com - partition with quorum

Online: [ node1.a.com node2.a.com ]
提供高可用服务
在corosync中，定义服务可以用两种借口
1.图形接口 （使用hb—gui）
2.crm （pacemaker 提供,是一个shell）
[root@node1 corosync]# crm configure show
node node1.a.com
node node2.a.com
property $id="cib-bootstrap-options" \
dc-version="1.1.5-1.1.el5-01e86afaaa6d4a8c4836f68df80ababd6ca3902f" \
cluster-infrastructure="openais" \
expected-quorum-votes="2"
用于查看cib的相关信息
如何验证该文件的语法错误
[root@node1 corosync]# crm_verify -L
crm_verify[32397]: 2012/10/20_13:24:12 ERROR: unpack_resources: Resource start-up disabled since no STONITH resources have been defined
crm_verify[32397]: 2012/10/20_13:24:12 ERROR: unpack_resources: Either configure some or disable STONITH with the stonith-enabled option

可以看到有stonith错误，在高可用的环境里面，会禁止实用任何支援
