The Swap Area Isn't Working

When you boot (or enable swapping manually) you should see

Adding Swap: NNNNk swap-space

If you don't see any messages at all you are probably missing

swapon -av

(the command to enable swapping) in your /etc/rc.local or /etc/rc.d/*
(the system startup scripts), or have forgotten to make the right
entry in /etc/fstab:

/dev/hda2 none swap sw

for example.

If you see:

Unable to find swap-space signature

you have forgotten to run mkswap. See the manual page for details; it
works much like mkfs.

Running, free in addition to showing free memory, should display:

total used free
Swap: 10188 2960 7228

If typing "cat /proc/swaps" reveals only file or partition names, but
no swap space information, then the swap file or partition needs
re-initialization.

Use fdisk (as root) to determine which partition on a hard drive has
been designated as the swap partition. The partition still needs to be
initialized with mkswap before enabling it with swapon.
