1) swapon -s (status)
2) swapon /dev/hd?? (substitute applicable partition)

"man swapon" for edification

run gkrellm and you can monitor swap usage.my swap isn't being used,but that's a good thing.it simply means my system has enough ram to not need it.

If you have a lot of ram, swap may not be used by your system.

ok this is whats still confusing.

when i shutdown the computer and watch all the text when linux is shutting itself down im pretty sure i see on the left hand side where it says shutting down swap then over on the right hand side i see "missing" in red.

when i did swapon -s it said /dev/hdb5
and swapon /dev/hdb5 told me device was busy
and when i tried man swap it said "no manual entry for swap"

I also have a monitor program on my desktop so i can see how much memory and swap is used and ive never seen it used on this installation and i know it should have because i purposely multitasked with gimp, mathematica, open office, and many more.

i have 512mb of ram so i im pretty sure i should have used swap space when multitasking because when i had 9.2 i did use it in similar situations

thanks

could there be any problems with the swap being on the extended partition instead of its own primary?

thanks

No - this is looking like a Suse problem. See also this thread.

As far as I remember I got that message a couple of times too. But only at shutdown and not always. I think it is more valuable to know if swap is set-up on boot. Try 'dmesg | grep swap' to see if swap has been activated.
Code:
user@linux:~> dmesg | grep swap
Adding 530104k swap on /dev/sda7.  Priority:42 extents:1
Is this the case, I wouldn't worry too much about the shutdown message. BTW: It's 'man swapon', not 'man swap'
