How do I extend LUKS partition to fill the whole logical volume of 2 disks on LVM?

I have added a second disk to my LVM system. I created a physical volume there, added it to the volume group of ubuntu, 'vgubuntu', extended logical volume to fill the whole disk. How do I extend the LUKS system partition to fill the whole logical volume? Here's more info provided by pvdisplay, vgdisplay and lvdisplay:
