How to add new hard drives, partitions, and mounts under Linux

Let's first talk about disk mounting on linux systems. After reading a lot of official help documents, it is troublesome not to mention technical operation errors, but it is quite complicated and difficult to understand for novices.

After my own slow exploration, I sorted out several simple and practical passwords to mount the disk.

1. Mount the disk (enter the password in a single line, please ignore this section if you do not have additional data disks)

1.fdisk -l

2.mkfs.ext4 /dev/vdb

3.echo '/dev/vdb /home ext4 defaults 0 0' >> /etc/fstab

4.mount -a

5.df -h

Note: Pay attention to backup important data before mounting the corresponding directory.

Check the disk label that needs to be mounted (you can see the disk label/devdb in the red box in the middle).

Enter the password: mkfs.ext4 /dev/vdb (create the partition in EXT4 format and format it).

Enter the password: echo/dev/vdb /home ext4 defaults 00/etc/fstab (echo/dev/vdb /home Connect the disk to the HOME directory.

Enter the password: mount -a (Mount the disk and check the disk status)

At this time, you can see that the capacity of the HOME directory has been increased and the disk is suspended.

If you want to mount the disk to another directory, you can change/home to any directory you want to mount it.
