# linux磁盘挂载

#### 进行挂载磁盘准备：

```
# 查看磁盘
fdisk -l
# 格式化磁盘 
mkfs.ext4 /dev/vdb
```

#### 创建挂载点：

在Docker的数据目录下创建挂载点,用于挂载硬盘分区。

```
sudo mkdir -p /trasen
```

#### 挂载硬盘分区：

使用mount命令将格式化的硬盘分区挂载到创建的挂载点。

```
sudo mount /dev/vdb /trasen
```

#### 设置挂载自动化

可以在/etc/fstab文件中设置启动时自动挂载,避免每次重启后手动挂载。

```
blkid /dev/vdb
# 输出结果
/dev/sdb: UUID="xxx-xxx" TYPE="ext4"
# 编辑文件
vim /etc/fstab
#添加如下内容
UUID=f51c5584-1d66-487e-be2d-3442b9bb058e /trasen    ext4    defaults    1 2
```
