ubuntu-services挂载外置硬盘

软件包升级
sudo apt upgrade

lsblk命令用于列出所有可用的存储设备及其分区信息

df -h 查看挂载点、文件系统类型、已用空间、可用空间等。

```bash
root@dellevin-ubuntu:/# lsblk

可以看到sdb并没有挂载

`sudo mkfs.ext4 /dev/sdb1` 将这块硬盘格式
化为 `ext4` 文件系统

```bash
root@dellevin-ubuntu:/mnt# sudo mkfs.ext4 /dev/sdb1

`sudo mount /dev/sdb1 /mnt/500Data` 创建挂载点并挂载硬盘

```bash
root@dellevin-ubuntu:/mnt# mkdir 500Data
root@dellevin-ubuntu:/mnt# ls
500Data
root@dellevin-ubuntu:/mnt# sudo mount /dev/sdb1 /mnt/500Data
root@dellevin-ubuntu:/mnt# df -h | grep sdb1

```

设置开机自动挂载

`sudo blkid | grep /dev/sdb1` 查看硬盘UUID

```bash
root@dellevin-ubuntu:/mnt/500Data# sudo blkid | grep /dev/sdb1
/dev/sdb1: UUID="86424462-d372-4894-89b2-3186bb52b237" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="1ea79eea-01"
```

`vim /etc/fstab` 然后编辑 `fstab`  添加一行：

```bash
UUID=86424462-d372-4894-89b2-3186bb52b237  /mnt/500Data   ext4   defaults   0   2
```
