- Assuming you created partition /dev/sda3, let's now create the physical volume in that partition:

- Now let's extend the server's Volume Group to that physical volume.

This will give you the info on your current Volume Group. Note down the entry next to "VG Name". That's your Volume Group name.

If you get a message saying /dev/sda3 could not be added to your Volume Group, you need to remove the physical volume and  recreate it. Metadata might have gotten corrupt and thus the volume cannot be added to your Volume Group. So just do:

- Since we're (essentially) extending the main logical volume, let's get the name of that:

$ lvextend -L +XG yourLogicalVolumeName

Make sure you replace X above with the actual number of GBs you've added in your VM's settings. So if you increased your VM by  20GBs, the command becomes:
