Linux Getting Started Basics (v) Linux file system mount management

Mount an operation disk or partition after you create a file system, you need to mount to a directory to be able to use it.

Windows or Mac systems mount automatically, and once the file system is created, it is automatically mounted on the system, which is called C disk, D disk, etc.

Linux requires manual mount operation or configuration system for automatic mount

For example,/dev/sda3 ext4-is mounted under/MNT to use system recommendations to mount to/MNT, but it is actually possible to mount anywhere.

New Mount/dev/sda2 to/mnt in read-only mode

Umount command

Command Umount is used to uninstall the mounted file system, rather with Windows pop-up Umount file System/mount point $ umount/dev/sda2/mnt

The situation may occur/mnt:device is busy. Indicates that the file is in use and cannot be unloaded

You can view the process using the file system with the following command: $ fuser-m/mnt

You can also use the command lsof to view the file that is being used $ lsof/mnt (mount point)

Automatic mount

The profile/etc/fstab is used to customize the file system that needs to be mounted automatically, and each row in the Fstab represents a mount configuration, in the following format:/dev/sda2/mnt/ext4/defaul TS 0 0 Mounting Device mount point file system Mount option dump, fsck related options

Devices that need to be mounted can also be identified using a label, using Label=shuangde instead of/dev/sda2 for example: lable=shuangde/mnt ext4 NOATIME,RW 0 0

The MOUNT-A command mounts the automatic mount options defined in all Fstab
