ubuntu磁盘挂载

1. 临时挂载

# 查看磁盘分区情况
lsblk	

# 查看磁盘类型：固态硬盘还是机械硬盘，rota=1的为机械硬盘
lsblk -d -o name,rota
示例：
ubuntu@ubuntu-QiTianM435-B698:~$ lsblk -d -o name,rota
NAME    ROTA
loop0      1
loop1      1
loop2      1
loop3      1
loop4      1
loop5      1
loop6      1
loop7      1
loop8      1
loop9      1
loop10     1
loop11     1
loop12     1
loop13     1
loop14     1
loop15     1
loop16     1
loop17     1
loop18     1
loop19     1
loop20     1
sda        1
nvme0n1    0

# 创建挂载目录
sudo mkdir /hdd 
# 挂载磁盘
sudo mount /dev/sda3/ /hdd
# 取消挂载
umount /dev/sda3/ /hdd

2. 永久挂载

临时挂载的话如果系统重启那么挂载会失效，需要重新挂载。因此可以利用永久挂载。

# 获取分区的uuid和磁盘类型
sudo blkid /dev/sda3
示例：
ubuntu@ubuntu-QiTianM435-B698:~$ sudo blkid /dev/sda3
/dev/sda3: UUID="353cde65-779d-4c8d-8c38-aab02fe1823e " TYPE="ext4" PARTUUID="59b8df38-4094-4bbc-a21c-5fcaa0c2d16f"
# 创建挂载点
sudo mkdir /hdd 
# 编辑/etc/fstab 文件
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. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda4 during installation
UUID=60489bd8-7a5f-47f0-9f1b-1d76393848c8 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/nvme0n1p1 during installation
UUID=D624-BC90  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0
                                                                                 

在文末加上一行：

# 格式：<UUID> <挂载点> <文件系统> <挂载选项> <dump> <fsck>
UUID=353cde65-779d-4c8d-8c38-aab02fe1823e /hdd ext4 defaults,noatime,nofail 0 0

# 检查挂载是否正确
sudo mount -a

重启系统后也能发现磁盘挂载上去了。
