Cant Mount a Swapfile

So basicly i can't use a Swap partition as all my partitions on my dos partition table are used up. That's why i would like to use a swapfile. I'm running a Brtfs is that matters. I also tried this with a subvolume but it gave me the same error as with this. Also the same thing happens when i run it as root directly. idk what to do anmore.

[leon@arch ~]$ sudo swapon /swapfile
swapon: /swapfile: swapon failed: Invalid argument

[leon@arch ~]$ sudo swapon --version
swapon from util-linux 2.39.2

Re: Cant Mount a Swapfile

It does matter that you're running on btrfs, see the note at https://wiki.archlinux.org/title/Swap#Swap_file and follow the instructions on the linked btrfs page
