6、创建文件系统并挂载（主节点Node1）
文件系统的挂载只能在Primary节点进行，因此在主节点上对drbd设备进行格式化：
# mke2fs -j /dev/drbd0
# mkdir /mydata
# mount /dev/drbd0 /mydata
7、切换主从节点进行测试
Node1:
# cp /etc/inittab /mydata
# umount /mydata
# drbdadm secondary mydrbd
# drbd-overview
0:mydrbd Connected Secondary/Secondary UpToDate/UpToDate C r-----
Node2:
123456 # drbdadm primary mydrbd
# drbd-overview
0:mydrbd Connected Primary/Secondary UpToDate/UpToDate C r-----
# mkdir /mydata
# mount /dev/drbd0 /mydata
# ls /mydata
8、配置openais/corosync+pacemaker
<1> 安装corosync和pacemaker（SteppingStone）
# cd /root/corosync/
# ls
cluster-glue-1.0.6-1.6.el5.i386.rpm
cluster-glue-libs-1.0.6-1.6.el5.i386.rpm
corosync-1.2.7-1.1.el5.i386.rpm
corosynclib-1.2.7-1.1.el5.i386.rpm
heartbeat-3.0.3-2.3.el5.i386.rpm
heartbeat-libs-3.0.3-2.3.el5.i386.rpm
libesmtp-1.0.4-5.el5.i386.rpm
pacemaker-1.1.5-1.1.el5.i386.rpm
pacemaker-libs-1.1.5-1.1.el5.i386.rpm
resource-agents-1.0.4-1.1.el5.i386.rpm
# step 'mkdir /root/corosync'
# for I in {1..2};do scp *.rpm node$I:/root/corosync;done
# step 'yum -y --nogpgcheck localinstall /root/corosync/*.rpm'
# step 'mkdir /var/log/cluster'
<2> 修改corosync配置并密钥认证（Node1）
1234567891011121314151617181920 # cd /etc/corosync/
# cp corosync.conf.example corosync.conf
# vim corosync.conf
# 修改如下内容：
secauth: on
threads: 2
bindnetaddr: 192.168.1.0
to_syslog: no
# vim corosync.conf
# 添加如下内容：
service {
ver: 0
name: pacemaker
}
aisexec {
user: root
group: root
}
# corosync-keygen
# scp -p authkey corosync.conf node2:/etc/corosync/
<3> 启动服务并检查（Node1）
# service corosync start
# ssh node2 'service corosync start'
# grep -e "Corosync Cluster Engine" -e "configuration file" /var/log/cluster/corosync.log
# grep TOTEM /var/log/cluster/corosync.log
# grep pcmk_startup /var/log/cluster/corosync.log
<4> 配置集群属性
禁用stonith设备、关闭法定票数策略、设置默认粘性：
# crm configure property stonith-enabled=false
# crm configure property no-quorum-policy=ignore
# crm configure rsc_defaults resource-stickiness=100
查看集群配置：
# crm configure show
node node1.linuxidc.com
node node2.linuxidc.com
property $id="cib-bootstrap-options" \
dc-version="1.1.5-1.1.el5-01e86afaaa6d4a8c4836f68df80ababd6ca3902f" \
cluster-infrastructure="openais" \
expected-quorum-votes="2" \
stonith-enabled="false" \
no-quorum-policy="ignore"
rsc_defaults $id="rsc-options" \
resource-stickiness="100
9、将已经配置好的drbd设备/dev/drbd0定义为集群服务
<1> 停止drbd服务并关闭自启动（Node1和Node2）
# service drbd stop
# chkconfig drbd off
<2> 配置drbd为集群资源（Node1）
添加mydrbd资源并设置为主从资源：
# crm configure primitive MySQLdrbd ocf:linbit:drbd params drbd_resource=mydrbd op start timeout=240 op stop timeout=100 op monitor role=Master interval=20 timeout=30 op monitor role=Slave interval=30 timeout=30
# crm configure ms ms_mysqldrbd mysqldrbd meta master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true
注：高可用资源不可与drbd资源重名；crm status如显示出错，则检查配置后重启corosync服务即可
查看当前集群运行状态：
# crm status

将node1设置为standby，则资源转移至node2
