实验环境（client node1 node2）

1.创建复制式的卷

gluster volume create v2 replica 2 node1:/data/xx node2:/data/xx force
[root@node1 ~]# gluster volume create v2 replica 2 node1:/data/xx node2:/data/xx force
volume create: v2: success: please start the volume to access data

2.查看v2卷的信息

[root@node1 ~]# gluster volume info v2
 
Volume Name: v2
Type: Replicate
Volume ID: b0fd721d-ec9e-4431-916b-8136e48cf9ed
Status: Created
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: node1:/data/xx
Brick2: node2:/data/xx
Options Reconfigured:
performance.readdir-ahead: on

3.开启v2

[root@node1 ~]# gluster volume start v2
volume start: v2: success

4.用客户端挂载v2

[root@client /]# mount node1:/v2 /v2
[root@client /]# df -hT
文件系统       类型      容量  已用  可用 已用% 挂载点
/dev/vda1      xfs        20G  1.3G   19G    7% /
devtmpfs       devtmpfs  488M     0  488M    0% /dev
tmpfs          tmpfs     497M     0  497M    0% /dev/shm
tmpfs          tmpfs     497M  6.7M  490M    2% /run
tmpfs          tmpfs     497M     0  497M    0% /sys/fs/cgroup
tmpfs          tmpfs     100M     0  100M    0% /run/user/0
node1:/v2      nfs       2.0G   32M  2.0G    2% /v2

5.我们尝试建立100个文件，来测试是不是复制式的卷。

[root@client v2]# touch test{1..100}.txt
[root@client v2]# ls

OK，node1和node2中各有100个文件，说明复制式的卷已创建好。
