partition

I've already resized my virtual disk with VirtualBox, but now need to extend the partition of my Ubuntu VM itself.

I thought I was on my way with GParted live CD, but after I resize the "extended" filesystem partition, and then the child "lvm2 pv" filesystem partition to fill the unallocated space, df -h still shows the original disk size after I reboot into the VM.

Any tips on this? I've scoured the webs tirelessly. Should I be resizing the boot (/dev/sda1) partition instead? Should I try to convert my lvm2 to ext4 or something? I'm lost on this.

attached screenshot

Note: VirtualBox hard disk is "dynamic".

Specs: VBox 4.2.18 Ubuntu 12.04.2 amd64 Gparted 0.16.2-1b-i486
