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
