If that volume is not in use by anything else you should be perfectly able to do:
mkswap /dev/VolGroup00/swap swapon /dev/VolGroup00/swap
then add something like this to fstab: /dev/VolGroup00 swap swap defaults
0 0
Shouldn't the fstab entry be:
/dev/VolGroup00/swap swap swap defaults 0 0
Just want to double-check before I dive in.
Thanks
