mount 目录挂载

将 /dev/sda1 对应的 /media/w/9f6a2add-e287-4bf7-8e71-76cde406b11c 目录内容挂载到 /mnt/sda1 目录中，使用 sudo mount /dev/sda1 /mnt/sda1 命令


w@w:/mnt/sda1$ df -h

注意

这样挂载完以后的目录，电脑重启后挂载的内容就没有了，需要重新操作，解决方式如下

使用 root 用户在 /etc/fstab 文件中添加一行内容 /dev/sda1 /mnt/sda1 ext4 errors=remount-ro 0 1 这样电脑重启后挂载的目录依然还在。

root@w:~# tail /etc/fstab
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sdb2 during installation
UUID=b9bceef6-f44c-4882-9216-1d6b8ecf1e43 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sdb1 during installation
UUID=5B15-2493  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0

/dev/sda1 /mnt/sda1               ext4    errors=remount-ro 0       1

设备文件类型查询，使用 root 用户执行 blkid 命令

root@w:~# blkid
