Indeed, in the general case you'll need to do it like:
lvcreate --name tmpswap --size NNg <VG>
mkswap /dev/<VG>/tmpswap
swapon /dev/<VG>/tmpswap
swapoff /dev/<VG>/swap
lvresize --size +2g /dev/<VG>/swap
mkswap /dev/<VG>/swap
swapon /dev/<VG>/swap
swapoff /dev/<VG>/tmpswap
lvremove /dev/<VG>/tmpswap
but in my case, the need to resize was typically when hibernate failed
because the swap was not sized accordingly, so I could just do:
swapoff /dev/<VG>/swap
lvresize --size +2g /dev/<VG>/swap
mkswap /dev/<VG>/swap
swapon /dev/<VG>/swap
[ Sadly --resizefs doesn't work on a swap partition, AFAICT. ]
