Hey Jeff,

The swap partitions are setup by `swapon -a' in /etc/rc.d/rc.sysinit,
which will initialize any swap partition listed in /etc/fstab with type
"swap" or "sw":

/dev/hda6             swap      swap    defaults 0 0

You can check for swap partitions by running `sfdisk -l /dev/hda' and
looking for partition type 82, but if you are on a raid system it isn't
that obvious--by default Cobalt uses /dev/md6 for raid.

If the partition type is set to 82, then you can try enabling it with
`swapon -v /dev/hda6' but if that fails then its possible the swap
partition is corrupt and can be rebuilt with `mkswap -c /dev/hda6'
(the -c option checks for bad blocks first)

The active (if any) swap partitions are listed in /proc/swaps and can
also be listed with `swapon -s'.

Good luck,
