1. `lsblk`: This command will list all block devices (block devices), that is, disks and disk partitions. It can help you find the device ID of your data disk.
2. `fdisk /dev/vdb`: This command will open a program used to operate disk partitions. `/dev/vdb` is the device identifier of your data disk. In this program, you can use various commands to operate.
- `m`: Show all available commands.
- `n`: Create a new partition.
- `p`: Print the partition table, that is, display all partitions.
- `w`: Save changes and exit.
3. `mkfs.ext4 /dev/vdb1`: This command will format the first partition of your data disk (`/dev/vdb1`) using the ext4 file system.
4. `mkdir /data`: This command will create a new directory `/data`, which will be used as the mount point of the data disk.
5. `mount /dev/vdb1 /data`: This command will mount the first partition of your data disk (`/dev/vdb1`) to the `/data` directory.
6. `echo "/dev/vdb1 /data ext4 defaults 0 0" >> /etc/fstab`: This command will add a line to the end of the `/etc/fstab` file. This file is used to control which devices will be automatically mounted when the system starts. The meaning of this line is that every time the system starts, `/dev/vdb1` will be mounted to the `/data` directory. The file system type is ext4, the mount option is defaults, the dump backup is set to 0, and fsck checks The priority is 0.
7. `df -h`: This command will display the disk usage of all mounted file systems. The `-h` option will display the size in human readable form, such as KB, MB, GB, etc.
8. `lsblk`: Run the `lsblk` command again to verify that your data disk has been successfully mounted to the `/data` directory.
