Virtualbox modifies the Virtual Machine disk VDI size

During the use of virtual machines, sometimes the disk size is insufficient. If you set "Dynamic Storage Allocation", you can manually expand the disk space using the following method.

1. Start the CMD command line to enter the virtualbox installation directory. For example

Cd e: \ Program Files \ oracle \ virtualbox

2. view the virtual hard disk to be modified:

E: \ Program Files \ oracle \ virtualbox> vboxmanage.exe list hdds
UUID: e8e2c341-b3b1-49db-ad2d-ab4e6b08bc5a
Parent UUID: Base
State: Locked write
Type: normal (base)
Location: F: \ VM \ CentOS-64.vdi
Storage Format: VDI
Capacity: 8000 Mbytes

Type: normal (base)
Location: F: \ VM \ CentOS-64-ext.vdi
Storage Format: VDI
Capacity: 21273 Mbytes

We see there are three Virtual Disks, we want to modify the first in the figure, its space size is 8 GB, UUID: e8e2c341-b3b1-49db-ad2d-ab4e6b08bc5a

2. Adjust the disk space to 15 GB:

E: \ Program Files \ oracle \ virtualbox> vboxmanage.exe modifyhd e8e2c341-b3b1-49db-ad2d-ab4e6b08bc5a -- resize 150000%... 10%... 20%... 30%... 40%... 50%... 60%... 70%... 80%... 90%... 100%
3. Check again:
E: \ Program Files \ oracle \ virtualbox> vboxmanage.exe list hddsuuid: e8e2c341-b3b1-49db-ad2d-ab4e6b08bc5aParent UUID: basestate: Locked writetype: normal (base) Location: F: \ VM \ CentOS-64.vdiStorage format: vdicapacity: 15000 Mbytes

4. view new disk space
Restart the VM to view the disk status.
[[Email protected] ~] # Fdisk-L/dev/SDA
Disk/dev/SDA: 15.7 GB, 15728640000 bytes255 heads, 63 sectors/track, 1912 Cylinders
 
We can see that the disk space has been extended to 15 GB, but it cannot be used yet.
5. New enable space
Use fdisk to create the free space of the virtual disk as a new partition. Note that the partition code 8e representing Linux LVM should be used as the ID.
# Fdisk/dev/SDA
N {New partition}
P {primary partition}
3 {Partition Number}
T {change partition ID}
3 {Partition Number}
8e {Linux LVM partition}
W
------
If there is a prompt such as setting the size in the middle, press Enter.
6. Check whether the newly added sda3 is marked as LVM. If no reboot is required
# Fdisk-L/dev/SDA
7. Adjust LVM size
Let's take a look at volume group.
[[Email protected] ~] # Vgdisplay --- volume group --- VG name vg_aimin
....
8. Create a new physical volume for the newly allocated space
# Pvcreate/dev/sda3
 
9. Adjust the logical volume size
# Resize2fs/dev/vg_aimin/lv_root
Now the space is expanded.
