Cannot increase swap file size

Issues & Assistance
1

I just installed a fresh copy of Reborn and have everything setup to my liking, all my software in and it’s looking good. I chose to install on BTRFS with swap file. I just went to in crease the swap file from 512 megs to 8 gigs and it fails. Any thoughts? Thanks

The swap is apparently not active, based on what I see in your output. It seems like the swapfile you made earlier is different from the one in fstab. Follow these instructions for swapfile creation: Swap - ArchWiki

OK from what you’re seeing is there anything I should remove before doing that? Like that fstab entry maybe, or the file that was created?

If you have sufficient RAM available, you can turn off swap and remove both, and then create it anew
