首先查看一下磁盘信息
lsblk
llxy@llxy-GS65-Stealth-9SD:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT ...(省略 sda 8:0 0 7.3T 0 disk ├─sda1 8:1 0 3.8G 0 part /media/llxy/32594cb4-2fba-402f-93ca-910eb2a8cc42 ├─sda2 8:2 0 193.2G 0 part /media/llxy/c6a44be7-232a-45ad-b1cf-eb75a8c16814 ├─sda3 8:3 0 456.4G 0 part /data1 ├─sda4 8:4 0 3T 0 part /media/llxy/1acd2865-ea43-4fb2-a56a-192e43d23e94 ├─sda5 8:5 0 3.5T 0 part /media/llxy/4efedcff-6b6e-4d4d-b8f6-e337440af04a └─sda6 8:6 0 186.3G 0 part ...(省略
可以看到sda下的sda3现在已经是挂载在/data1下，sda下其他磁盘还没有被挂载在Ubuntu
临时挂载（重启就会取消挂载）1. 创建挂载目标文件（如果有可以省略）
sudo mkdir /test-mount
2. 查看磁盘信息
df -h
llxy@llxy-GS65-Stealth-9SD:~$ df -h 文件系统 容量 已用 可用 已用% 挂载点 ...(省略 /dev/sda2 190G 61M 180G 1% /media/llxy/c6a44be7-232a-45ad-b1cf-eb75a8c16814 /dev/sda4 3.0T 89M 2.9T 1% /media/llxy/1acd2865-ea43-4fb2-a56a-192e43d23e94 /dev/sda5 3.5T 89M 3.3T 1% /media/llxy/4efedcff-6b6e-4d4d-b8f6-e337440af04a
比如我想要挂载sda2，主要看最前面的信息，sda2的文件路径是/dev/sda2
3. 挂载
sudo mount /dev/sda2 /test-mount
4. 查看挂载信息
llxy@llxy-GS65-Stealth-9SD:/$ df -h 文件系统 容量 已用 可用 已用% 挂载点 ...(省略 /dev/sda2 190G 61M 180G 1% /test-mount /dev/sda4 3.0T 89M 2.9T 1% /media/llxy/1acd2865-ea43-4fb2-a56a-192e43d23e94 /dev/sda5 3.5T 89M 3.3T 1% /media/llxy/4efedcff-6b6e-4d4d-b8f6-e337440af04a
永久挂载
比如想要永久挂载sda1，利用
df -h
得到路径为/dev/sda1
1. 查看磁盘的UUID
llxy@llxy-GS65-Stealth-9SD:~$ sudo blkid ...（省略 /dev/sda1: UUID="32594cb4-2fba-402f-93ca-910eb2a8cc42" TYPE="ext4" PARTUUID="611cb9f8-90ab-4324-a5c4-bc07bc775aad" /dev/sda2: UUID="c6a44be7-232a-45ad-b1cf-eb75a8c16814" TYPE="ext4" PARTUUID="fd4844c5-da0b-49a4-af19-c453384d4bc0" /dev/sda3: UUID="0614ebf3-448b-4b8c-91e1-3094372ade8e" TYPE="ext4" PARTUUID="43e4ed90-d413-4137-bfb7-1dbcac173a73" /dev/sda4: UUID="1acd2865-ea43-4fb2-a56a-192e43d23e94" TYPE="ext4" PARTUUID="cb85ffea-5442-4e7e-8b8d-cc2744938fbb" /dev/sda5: UUID="4efedcff-6b6e-4d4d-b8f6-e337440af04a" TYPE="ext4" PARTUUID="ecd81725-b79e-4767-a3b2-16ff1a16747e" /dev/sda6: UUID="5dffdcd2-2fff-40c1-8bdf-c571a200102d" TYPE="swap" PARTUUID="af6acae9-a819-4608-b1f4-9c8187dcae20" ...（省略
通过上面的命令找到/dev/sda1的UUID，最好复制一下
- 编辑/etc/fstab文件
llxy@llxy-GS65-Stealth-9SD:~$ sudo vim /etc/fstab
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

参数含义
这里需要配置6个参数，file system，mount point，type，options，dump，pass；
-
file system
文件系统，参考默认的fstab来看，这里只需要把硬盘的UUID正确配置即可；可以通过指令blkid，查看硬盘的UUID；
-
mount point
挂载路径，最终硬盘会被挂载到配置的这个路径下，但是这个路径必须先存在，提前创建好这个路径即可；
-
type
硬盘的文件系统类型，相应的有ntfs，ext4，fat，vfat等等，这里要根据实际情况设置，同样的也可以通过指令blkid，查看硬盘的TYPE；
-
options
option----------------------description defaults--------------------use default options: rw, suid, dev, exec, auto, nouser, and async. noauto---------------------do not mount when “mount -a” is given (e.g., at boot time) user------------------------allow a user to mount owner----------------------allow device owner to mount comment or x- ----------for use by fstab-maintaining programs nofail-----------------------do not report errors for this device if it does not exist.
-
dump
这个参数用来检查文件系统以多快频率进行备份，系统将认为其值为0，则不需要进行备份；设置成1暂时也没有实践过；
-
pass
这个参数用来决定在启动时需要被fsck扫描的文件系统的顺序，根文件系统"/"对应该字段的值应该为1，其他的应该逐渐递增，如果设置为0则表示不扫描。
- 更新
sudo mount -a
- 检查

挂载成功
注意事项
如果报错情况可能需要如下操作：
a. 解挂载
llxy@llxy-GS65-Stealth-9SD:/$ sudo umount /test-mount llxy@llxy-GS65-Stealth-9SD:/$ df -h 文件系统 容量 已用 可用 已用% 挂载点 ...(省略 /dev/sda2 190G 61M 180G 1% /media/llxy/c6a44be7-232a-45ad-b1cf-eb75a8c16814 /dev/sda4 3.0T 89M 2.9T 1% /media/llxy/1acd2865-ea43-4fb2-a56a-192e43d23e94 /dev/sda5 3.5T 89M 3.3T 1% /media/llxy/4efedcff-6b6e-4d4d-b8f6-e337440af04a
b. 格式化
llxy@llxy-GS65-Stealth-9SD:/$ sudo mkfs -t ext4 /dev/sda2
c. 再次进行上面的挂载步骤即可成功（这里举例为临时挂载，永久挂载也是同理）
