**3.确认订单等待自动挂载**

**4.返回实例，就能看到刚刚够买的数据盘**

**5.查看已挂载数据盘情况**  
df -lh  
**6.查看所有数据盘包括未挂在的数据盘**  
fdisk -l

**7.对数据盘进行分区。**  
fdisk /dev/vdb  
①输入 n 并按回车键：创建一个新分区。  
②输入 p 并按回车键：选择主分区。因为创建的是一个单分区数据盘，所以只需要创建主分区。  
③输入分区编号并按回车键。因为这里仅创建一个分区，直接回车采用默认值。  
④起始扇区，直接回车采用默认值  
⑤Last 扇区，直接回车采用默认值  
⑥输入 wq 并按回车键，开始分区。

**8.在新分区上创建一个文件系统**  
mkfs.ext3 /dev/vdb1

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM0MjkzNzcw_size_16_color_FFFFFF_t_70 6][]

**9.在最外层创建挂载目录，并执行挂载命令：**  
mkdir data  
mount /dev/vdb1 /data

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM0MjkzNzcw_size_16_color_FFFFFF_t_70 7][]

**10.修改fstab,以便系统启动时自动挂载数据盘,编辑fstab默认启动文件命令:**  
vi /etc/fstab  
在其中添加一行:  
/dev/vdb1 /data ext3 defaults 0 0

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM0MjkzNzcw_size_16_color_FFFFFF_t_70 8][]

**11.将缓存写入服务器**  
sync  
 **12.优雅的重启服务器，测试数据盘是否自动挂载**  
shutdown -r now

**13.重新查看已挂载数据盘情况**  
df -lh

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM0MjkzNzcw_size_16_color_FFFFFF_t_70 9][]
