$ echo '/dev/vdb /storage/bricks/1 xfs defaults 0 0' >> /etc/fstab
$ mount -a
$ mkdir /store/bricks/1/brick
```
**Check disks mounted**

```sh
$ df -h
Filesystem      Size  Used Avail Use% Mounted on

**Create the Replicated GlusterFS Volume**

```sh
$ gluster volume create gv0 \
  replica 3 \
  node1:/storage/bricks/1/brick \
  node2:/storage/bricks/2/brick 
  

volume create: gv0: success: please start the volume to access data

$ gluster volume start gv0

$  gluster vol list
dev
