Ubuntu – How to resize partition that is inside “Linux LVM” partition


How to resize partition that is inside "Linux LVM" partition in 13.10 Ubuntu? I transferred Ubuntu installation from 160GB to 500GB disk. I have successfully resized sda3 partition using Ubuntu LiveCd and GParted and now have no idea how to resize this "155 GB Block Device".
Here is how it looks like.

GParted is useless for this. You'll need to either use an assortment of text-mode tools (such as resize2fs and lvresize) or another GUI front-end, such as kvpm or system-config-lvm. I believe that both are available in the Ubuntu repositories. This article I wrote a while back goes into a bit more detail, but stops short of being a step-by-step tutorial.
