Thanks very much for the reply.

Well it doesn't show up when I do 'df':

[root at mail ~]# df -h

/dev/mapper/VolGroup00-LogVol00

/dev/mapper/VolGroup00-LogVol05
                      1.9G   35M  1.8G   2% /tmp

Also, as I said /dev/VolGroup00/swap is not listed in /etc/fstab, but it
is listed in /dev/mapper/. Is that good enough confirmation that it is
not in use?

I'm very curious how I managed to get into this situation, using the GUI
install method. Any ideas on that? I'd prefer not to be in this
situation again.

Thanks
