1 Add a new hard drive
Settings -> Storage -> SATA Controller -> Right-click, select "Add Virtual Hard Disk"
2 Restart the virtual machine
View the disk space of the existing system
fdisk -l
You can see the newly added virtual hard disk, generally named: Disk /dev/sdb
- To the newly added hard disk partition
fdisk /dev/sdb
Type m to see help information
Type n again for a new partition
Type p again to select the base partition
Type 1 again to create a partition
Enter
carriage return, carriage return
Type w and press enter
- format disk partition
Format /dev/sdb1 with ext4 format
mkfs.ext4 /dev/sdb1
- mount partition
Create a new mount point
mkdir /svn
Mount the new disk partition to the /svn directory
mount -t ext4 /dev/sdb1 /svn
View mounts
df -h
can see the newly added hard disk: /dev/sdb1
- Set up the automatic mount at boot and
modify the file
vi /etc/fstab
to add a line:
/dev/sdb1 /svn ext4 errors=remount-ro 0 1Complete

Welcome to fdisk (util-linux 2.23.2).
Changes will stay in memory until you decide to write them to disk.
Think twice before using the write command.
Device does not contain a recognized partition table
to create a new DOS disk label with the disk identifier 0x3c8bf852.
命令(输入 m 获取帮助)：m
命令操作
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
g create a new empty GPT partition table
G create an IRIX (SGI) partition table
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (enter m for help): n
