I had resized my root partition from 30gb to 70gb using gparted. But Ubuntu still shows that I have the same old disk size while gparted shows that I acually have 70gb and that the other 40gb is somehow used. How can I fix this?

Output of 'df -h':

This resizing was done using an ubuntu live usb. On a side note I realized later that Ubuntu was hibernated while the resizing was done. Might have something to do with that. –  Sidharth Mudgal Aug 7 '13 at 20:22

It looks like gparted did extend the partition but not the file system. You will have to do that manually (ext4fs can be extended on a running system, even the / system).

Open a terminal and type sudo resize2fs /. You will see something like "online-resize necessary" and then (after a few seconds) "the new size is ....".

Check the result with df -h once more - you should see the new size.
