VM - Resize a .vdi disk
I created a VM with 10G disk, after the Linux 7 installation, and the first upgrade, decided was better to increase the disk to 50GB.
This post , i'm sharing the steps and commands I ran to increase the disk size.
Software :
Host : Windows 10 Pro , Oracle VM 6.1.2
Guest : Red Hat Enterprise Linux Server release 7.1 (Maipo) / Oracle Linux Server release 7.1
Ok - the first step is to resize the *vdi disk on the host side.
Open a PowerShell console in the VM folder (Left Shift + Mouse Right Click on Windows)
Quick list and check on the files.

With the VM down, ran the commands , make a copy then resize to about 52GB.

After running the command we can see capacity is now about 50GB

Now inside the VM guest, the file system stills with old size, the df anf fdisk shows as below

I followed the approach :
1- recreate the partition /dev/sda2.
