> 11.挂载使用

创建文件，写入挂载配置
```shell
mount /dev/rbd0 /ceph
vim /etc/rbd_mount.conf
```

> 12.查看挂载
配置内容如下：

```shell
lsblk
rbd-harbor-pool
rbd-harbor-image /ceph
```

> 13.查看块设备映射
创建挂载脚本，

```shell
[root@localhost ~]# rbd device list
id pool namespace image snap device
0 rbd-demo-pool rbd-demo-image - /dev/rbd0
mkdir -p /etc/init.d
vim /etc/init.d/ceph-mount-rbd.sh
```

> 14.修改`fstab`，设置开机挂载
内容如下：

```shell
echo "/dev/rbd0 /ceph ext4 defaults,noatime,_netdev 0 0" >> /etc/fstab
```

> 15.配置开机自启动
```shell
vim /etc/init.d/rbdmap
```

## lvm架构

![](lvm.png)
![](lvm.png)

### 创建lvm

1. 创建pv

```shell
pvcreate /dev/sdb
```

2. 创建vg

```shell
vgcreate data-volume /dev/sdb
```

3. 创建lv（逻辑卷）

```shell
lvcreate -n data-lv -l 100%free data-volume
```

4. 格式化lv

```shell
mkfs.ext4 /dev/data-volume/data-lv
```

5. 挂载使用

```shell
mkdir /data
mount /dev/data-volume/data-lv
```

6. 设置自动挂载

```shell
echo "/dev/data-volume/data-lv /data ext4 defaults 0 0" >> /etc/fstab
```
