前面创建盘的步骤省略 1.在节点A执行： sbd -d /dev/mapper/fence_lun001 -d /dev/mapper/fence_lun002 -d /dev/mapper/fence_lun003 -1 90 -4 360 create sbd -d /dev/mapper/fence_lun001 -d /dev/mapper/fence_lun002 -d /dev/mapper/fence_lun003 dump 2.在A/B/C/D上执行： service sbd stop cp /etc/sysconfig/sbd /etc/sysconfig/sbd_`date +%s` vi /etc/sysconfig/sbd
将：
SBD_DEVICE="/dev/mapper/fence_lun01;/dev/mapper/fence_lun02;/dev/mapper/fence_lun03"
替换为：
SBD_DEVICE="/dev/mapper/fence_lun001;/dev/mapper/fence_lun002;/dev/mapper/fence_lun003" service sbd start 3.在节点A执行：crm resource stop SBD_FENCE
crm configure
edit SBD_FENCE
修改为如下内容，更新盘符
primitive SBD_FENCE stonith:fence_sbd \ params devices="/dev/mapper/fence_lun001,/dev/mapper/fence_lun002,/dev/mapper/fence_lun003" action=reboot power_timeout=396 verbose=true \ meta target-role=Started is-managed=true verify ###只有校验成功才commit commit bye 启动sbd服务： crm resource start SBD_FENCE 4.在A/B/C/D上检查同步状态：
