I recently installed Fedora 20, and I forgot to adjust the swap partition size during install. It seems to have defaulted me to a size of 8G, but it did create a swap partition. Since I have 16G of RAM, I'd like to increase the swap to 32G, as I believe that's a good practice.

I've tried:

swapoff -v /dev/fedora/swap
lvresize /dev/fedora/home -L -16G
lvresize /dev/fedora/swap -L +16G
swapon -v /dev/fedora/swap

As directed in the Fedora docs, but according to both

free

and

cat /proc/swap

The swap partition is only 8G still. How can I do this without reinstalling Fedora?

This doesn't directly answer your question, but if I understand correctly you don't necessarily need that much swap; have a look at the Fedora 20 installation guide.

The answers here indicate how to add a partition or file for swap space. I want to expand what I currently have.

You can follow the steps described in the Fedora Documentation item "Adding Swap Space".

@Marc van der Wijst According to lvscan the sizes changed according what I provided, but not according to free or cat /proc/swaps.
