[Linux]vbox virtual machine Add new disk

That's the case, the hard drive setup was too small to start creating the virtual machine, only 10g, and I'm now adding a hard disk to this Linux (centos6.6) virtual machine with VBox settings.
The following action is how to mount the hard drive to the system.

Use Fdisk to view information about the physical disk now (this is done with root permission)

The following actions are root permissions.

Write Partition Table

The following is an interaction is a process, after each input according to the prompt, in the input

One more piece of partition information

formatting partitions

A command would be fine.

To create a new volume label (ignorable)

This step, I saw some people did, some people did not do, and then checked the information.
Can look at the reference E2label command
后面没用上，可以不操作的。

# e2label /dev/sdb1 /data

Check it out.

# e2label /dev/sdb1/data

Mount

Create a mount directory that is consistent with the previous step

mkdir /data

To automatically mount the boot, you also need to edit /etc/fstab the file, add a line after the file

/dev/sdb1       /data                   ext4    defaults        0 0

Some may not be familiar with this configuration file, see [Fatab Chinese explanation] (https://wiki.archlinux.org/index.php/Fstab_ (%e7%ae%80%e4%bd%93%e4%b8%ad%e6%96% 87)

Test

#Mount-a#DF-LHFilesystem            Size  used Avail  Use% mounted on/Dev/Mapper/Vg_orangleliu-Lv_root                      6.5G  3.2G  3.0G   the% /Tmpfs                 499M     0  499M   0%/dev/shm/Dev/sda1             477M    inM  424M   7%/boot/Dev/SDB1               -G    -M    -G   1%/data

Then reboot and view the mount condition again, normal mount, success.
