hello.
basically I missed setting /dev/hda2 as swap upon installation, trying to do it now.
I tried, following instructions online:
mkswap /dev/hda2
swapon /dev/hda2
and adding to /etc/fstab:
/dev/hdb2 swap swap defaults 0 0
rebooted, and swap is not used. at all.
swapon -s reveals that the priority is set to -1, tried using swapon to fix, no dice.
help?

According to this you have a problem:
swapon /dev/hda2
/dev/hdb2 swap swap defaults 0 0
Fix that and you should be good to go.

As Bigpaws indicated, if the command swapon /dev/hda2 works, your fstab line must also point to hda2, not hdb2

when I have it set to hda2, it is seen in swapon -s, but it is not used, and the priority is set to a negative, and some research indicates that a negative prioity= error.

According to this, a negative number is assigned by the kernel: http://lists.debian.org/debian-user/2002/09/msg01075.htmlLooking at my own system, "swapon -s" shows a -1 priority. "Used" shows 0, but that is normal. Only when I push my system hard and for a long time, do I ever use swap. Hint: run "htop" in a terminal to watch CPU/swap usage. |

Probably but I wouldn't recommend it. Swap is much slower than RAM. |
