If the swap partition is actually defined someplace, then adding it
to /etc/fstab and doing an /sbin/swapon as root should get it going.
However, if the partition scheme you setup doesn't include a swap
partition, then it may be best to get another small drive and shut it
down long enough to install it as /dev/hdc or /dev/hdd, keeping it
off the same cable the main drive is on. Then fdisk it to setup
enough of it as swap, some as /var and the rest as a backup storage
area like I did. Put it in the /etc/fstab, and do the swapon.
Another 2 to 3GB should be enough, and as its on a seperate drive, it
will be faster than thrashing the main drive.
Since drives don't come that small anymore, I moved /var to it too so
logging wouldn't go down when the darned thing went read-only on the
main drive when it got busy (& it hasn't since, with -rc4), and then
used the last 180GB of it as a virtual tape setup for amanda. Thats
what I did with a new 200GB a month ago, and its working right well.
You'll have to rig a copy of /var to the new drive while its mounted
to some temporary /mnt/xxx location, fix etc/fstab for the new /var
location and reboot to make the /var switch effective.
