IMO you're being blinded by /etc/fstab and -a. Rather, use /proc/swaps
to see what the kernel knows, and stop using -a. Cut and paste what
you do and the output, rather than all this "doesn't work" etc.

I'm guessing that on a parallel track, you need to examine the startup
files of whatever this beast is, presumably not Debian, and find some
occurrence of swapon that you can, in your jargon, "nuke".
