How to increase lvm size ( partitions already messed up )

edit

hi all i have two partitions one is used for f20 , and another is ntfs. i didn't know that gparted should not be used any more, and system-config-lvm has retired and not in repo anymore, so i boot up with live usb, and use gparted to resize ntfs partition and add free space to my fedora partition ( absurdly slow .. is this the correct way of doing it ? ). but the free space is not showing, so i ran the following command in live usb

lvextend -l 100%FREE /dev/mapper/fedora-root

after rebooting, the free space shown in df ~ or gparted is 100% , did i mess it up ? current gparted chart:
