I'm not sure with swap (I've never extended a swap partition). I know with other FS types you need to run that command to get the underlaying filesystem to fill the LV (otherwise it still reports it as the original size). Perhaps swap is different somehow (well I guess obviously it is as resize2fs doesn't even see an FS). I guess if it doesn't work as expected, perhaps google has some suggestions?
Let's hope it all works
