Use case

Due to history, there is not enough space in my Ubuntu system. I want to automatically mount an ext4 partition (/ dev/sda12) of my computer's built-in hard disk to the system in a way that users can read and write. My user's name is totoro.

Operation

Boot and mount the hard drive automatically: refer to the blog description and add to the last line of the / etc/fstab file

"UUID=XXX-XX / media/totoro/KylinData ext4 defaults 0 2" 1

Here is the partition of the specified UUID, mounted to / media/totoro/KylinData.

The first parameter is recommended to use UUID, because a partition has a unique UUID; with / dev/sdaN, but the partition number N of a partition will change with the partition of the hard disk, so it is not recommended. The console command to get UUID from / dev/sdaN is "sudo blkid (or: lsblk-f)".

However, this method is mounted as root, and the user and group in which the hard disk resides is changed to the current user:

Sudo chown-R totoro:totoro / media/totoro/KylinData/ sudo umount / media/totoro/KylinData

After reboot, it will be automatically mounted as the current user (not root)

Summary

The above is the operation method of Ubuntu16.04 ext4 format hard disk mounting ordinary user rights control introduced by Xiaobian. I hope it will be helpful to you.
