How to expand Ubuntu VM root partition

How to expand Ubuntu VM root partition

In this post I have expanded the virtual disk of a Ubuntu VM via VirtualBox Media Manager. The OS inside the VM will not automatically use the additional space. In this post I will show how to expand the root partition to make use of the additional space.

There are multiple ways to expand a partition in Linux, in this post I will document how to do it using GParted.

1.  Change the VM configuration to boot using Ubuntu installer. 
   
   
2. Boot the VM using the Ubuntu ISO installer
3. Run GParted - in the warning dialog that says not all space is used, hit on the Fix button
   
   
4. Select the partition to resize and click Resize/Move partition button
   
5. Expand the partition to the desired size
   
   
   
6. The hit on Apply All Operations
   
   
   
7. Shutdown the VM, remove/detach ISO, then reboot the computer
   

 

.end.
