手动切换连个节点状态，并进行挂载测试
[root@test01 ~]# umount /data

将test01手动提升至primary。并将/dev/drbd0进行格式化以供挂在使用
[root@test02drbd-utils-8.9.2]# drbdadm primary r1

现在drbd两个节点已经配置成功，并手动测试成功。drbd的两个节点，同时时间只有primary状态的节点提供服务。
1.3 配置nfs服务
test01 test02 web配置nfs的共享目录为/data ，test01 test02同时/dev/drbd0的挂载目录也是/data
1.3.1 将test01 drbd状态提升为primary并将/dev/drbd0挂载至/data,编辑/etc/exports文件，并本地测试。
[root@test01 ~]# cat/proc/drbd

1.3.2 将test01状态降为secondary，将test02状态提升为primary，并将/dev/drbd0挂载至/data，编辑/etc/exports文件，并本地测试
