Thanks for the suggestions, but qtparted does not help.

I ran Knoppix Live CD 3.7 which has qtparted 0.4.4 and it does not
recognizes the linux lvm partition and shows it as unknown
type/filesystem in the list, and it does not give any other information
or any other option(e.g resize) when i right click that partition.

so the question remains how to do it.
