heartbeat 2.x使用CRM进行集群资源和管理的工作，除了提供hb_gui图形管理工具外，还可以使用crm_resource程序进行管理。以下内容截取自：分享:heartbeat 2.x style的配置，供参考。

1)查看所有资源

    crm_resource -L

2)查看资源跑在哪个节点上

    crm_resource -W -r runhttpd.sh_2

    resource runhttpd.sh_2 is running on: server1

    crm_resource -W -r runhttpd.sh_2

    resource runhttpd.sh_2 is NOT running

4)启动/停止资源

    crm_resource -r runhttpd.sh_2 -p target_role -v started
    crm_resource -r runhttpd.sh_2 -p target_role -v stopped

5)查看资源在cib.xml中的定义

    crm_resource -x -r runhttpd.sh_2

6)将资源从当前节点移动向另个节点

    crm_resource -M -r runhttpd.sh_2

7)将资源移向指定节点

    crm_resource -M -r runhttpd.sh_2 -H c001n02

允许资源回到正常的节点

    crm_resource -U -r runhttpd.sh_2

NOTE: the values of resource_stickiness and default_resource_stickiness may mean that it doesnt move back. In such cases, you should use -M to move it back and then run this command.

9)将资源从CRM中删除

    crm_resource -D -r runhttpd.sh_2 -t primitive

10)将资源组从CRM中删除

    crm_resource -D -r my_first_group -t group

11)将资源从CRM中禁用

    crm_resource -p is_managed -r runhttpd.sh_2 -t primitive -v off

12)将资源从新从CRM中启用

    crm_resource -p is_managed -r runhttpd.sh_2 -t primitive -v on

13)Resetting a failed resource after having been manually cleaned up

    crm_resource -C -H c001n02 -r runhttpd.sh_2

14)检查所有节点上未在CRM中的资源

    crm_resource -P

15)检查指定节点上未在CRM中的资源

    crm_resource -P -H c001n02

Querying a parameter of a resource. Say the resource is the following:
<primitive id="example_mail" class="ocf" type="MailTo" provider="heartbeat">
    <instance_attributes id="example_mail_inst">
        <attributes>
            <nvpair id="example_mail_inst_attr0" name="email" value="root"/>
            <nvpair id="example_mail_inst_attr1" name="subject" value="Example Failover"/>
        </attributes>
    </instance_attributes>
</primitive>

You could query the email address using the following:
    crm_resource -r example_mail -g email

16)设置资源的某个属性

crm_resource -r example_mail -p email -v "[email protected]"
