increase virtual box VM size to 80GB

VBoxManage modifyhd '$HOME/VirtualBox VMs/UbuntuServer.vdi' --resize 81920

create a new PV

sudo fdisk -c /dev/sda --> the disk that you just expanded press -->

1. n,
2. 4(new partition number),
3. t

you will see a new partition added with all the free space avaiable on that disk. In my case it created sda4

Create a PV

sudo pvcreate /dev/sda4

list the VGs and expand the VG

sudo vgs
sudo vgextend ubuntu-vg /dev/sda4

  Volume group "ubuntu-vg" successfully extended

find the free space in the VG and expand the LV

sudo vgdisplay
sudo lvextend -L +49G /dev/mapper/ubuntu--vg-ubuntu--lv
sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
