It is not completely clear, at least to this reader,
exactly what flavor of *nix you have.
Some/many/most *nix do not require a dedicate partition for swap.
You can use dd to create a "swap file" on any volume you want &
include this new file to the existing swapspace.
(or at least I have done so multiple times.)
