Oracle VirtualBox - Resizing 'vmdk' disk

 

<Overview>

This is how to resize 'vmdk' file by CLI.

 

 

<Pre-Requisites>

1. Oracle VB should be installed

2. You should have a VM to resize.

 

<Steps>

1. My VM(controller) has 30.00GB 'vmdk' disk.

 

2. Check and go to the directory location that the disk is placed on.

Machine > Settings > Storage > Information > Location

 

 

3. Open a command prompt.

 

4. You should check the location for the command file(VBoxManage.exe) to resize.

In my case, I can see the file in here.

 

5. Change disk format from .vmdk to vdi

VBoxManage clonemedium "original.vmdk" "clone.vdi" --format vdi

 

6. Resize the cloned vdi disk.

1GB = 1024MB

500GB = 512,000MB

VBoxManage modifymedium "clone.vdi" --resize 512000

 

7. Change the cloned disk to vmdk format

VBoxManage clonemedium "clone.vmdk" "resize.vdi" --format vmdk

 

8. Replace the VM disk.

Machine > Settings > Storage > Attributes > Choose Virtual Hard Disk File... > resized.vmdk

 

9. Check the Disk size

 

That's a wrap!
