ubuntu磁盘挂载以及开机自动挂载

• 系统: Ubuntu 18.04
• 磁盘: 240GB nvme ssd

1. 磁盘挂载

1. 使用命令查看分区:

sudo fdisk -l

root@ubuntu:~/workspace# fdisk -l

• 可以根据上面提供的磁盘信息确定想挂载的磁盘。本次目的是将 /dev/nvme0n1 磁盘挂载到 /ssd 目录上

2. 创建挂载目录

sudo mkdir /ssd

3. 挂载

mount /dev/nvme0n1 /ssd

4. 查看:

sudo df -h

root@ubuntu:~# df -h

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        15G  4.7G  9.1G  35% /
devtmpfs        1.9G     0  1.9G   0% /dev
tmpfs           1.9G   22M  1.9G   2% /dev/shm
tmpfs           1.9G   17M  1.9G   1% /run

tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
tmpfs           385M   16K  385M   1% /run/user/1000
/dev/mmcblk2p1   15G  2.9G   13G  19% /media/ubuntu/7E1EC0F91EC0AC091
/dev/nvme0n1    234G   17G  206G   8% /ssd

2. 设置开机自动挂载

1. 查询目标磁盘UUID

sudo bljid /dev/nvme0n1

root@ubuntu:~# blkid /dev/nvme0n1
/dev/nvme0n1: UUID="8a1f77a3-6f4f-476b-9ac7-13f4299ed7ca" TYPE="ext4"

2. 修改系统配置文件:

sudo vim /etc/fstab

root@ubuntu:~# vim /etc/fstab


# UNCONFIGURED FSTAB FOR BASE SYSTEM
UUID=8a1f77a3-6f4f-476b-9ac7-13f4299ed7ca /ssd ext4 0 2

格式为： [UUID=**********************] [挂载磁盘分区] [挂载磁盘格式] 0 2

• 第一个数字 : 0表示开机不检查磁盘，1表示开机检查磁盘。
• 第二个数字 : 0表示交换分区，1表示启动分区(linux)，2表示普通分区

这里挂载的是ext4格式的磁盘
可以挂载windows系统下创建的分区，格式为ntfs
