Ubuntu 18.04使用GPT分区并挂载硬盘

进行sudo fdisk -l查看机器上都插了哪些安装盘，看到/dev/sda，并且没有进行分区。

这个时候是没有挂载的，运行如下命令：

• sudo parted /dev/sda #进入parted
• mklabel gpt #将磁盘设置为gpt格式，
• mkpart logical 0 -1 #将磁盘所有的容量设置为gpt格式
• print #查看分区结果
• quit #退出

root@XXX:~# sudo parted /dev/sda

(parted) quit

这个时候应该是默认进行分了一个/dev/sda1这个分区

• 运行sudo mkfs.ext4 -F /dev/sda1 将刚刚分出来的sda1格式化为ext4的格式，然后就可以设置开机自动挂载了。

设置挂载点

sudo mkdir /home/phd1 phd1为新文件名，文件名可自定义

执行 sudo nano /etc/fstab

在文件末尾添加

/dev/sda1 /home/phd1 ext4 defaults 0 0

使用sudo mount -a即可进行重新挂载
