基于ILO4的RHCS集群中fence配置

一、重要知识

ILO2 对应的fence agent是fence_ilo,ILO3,ILO4对应的fence agent是fence_ipmilan。

使用fence_ipmilan agent时，需要节点安装ipmitool工具，否则报错：

agent "fence_ipmilan" reports: ipmilan: ipmitool not found! failed: Failed to initialize。

二、fence_ipmilan调试指令

查看主机状态

fence_ipmilan -P -A password -l cluster -p hpinvent -o status -a 10.10.129.171

三、cluster.conf配置示例

<?xml version="1.0"?>
<cluster config_version="14" name="psql">
        <clusternodes>
                <clusternode name="trfdb01" nodeid="1">

                                <method name="ilo">
                                        <device name="fence_node1"/>
                                </method>
                        </fence>
                </clusternode>
                <clusternode name="trfdb02" nodeid="2">
                        <fence>

                                </method>
                        </fence>
                </clusternode>
