Something like the above?
Okay, I did that, and now I get "LI" when I booted up! What does "LI" in lilo mean? What part of my boot up sequence is broken?
Someone told me it meant my second stage boot loader was failing. What does that mean? What are the stages of booting? Can anyone hook me up here?
As far as I know, I have ReiserFS compiled into the kernel along with LVM support in the kernel.
I must admit ReiserFS has worked quite well for me, and is very bug-free. I am using the version that comes with the 2.4.8-12mdk (mandrake) kernel, so perhaps u tried an older version.

you need a normal partition vor /boot not on LV and it would be good to
have also a normal partition as swap,
but in case you don't use swap you don't need to,
the thing is that the swap is much faster when it is on partition not file
you can try to do it without formating the second disk
you can shrink ReiserFS, then with diskdrake shrink the partition
and make a new one for boot and for the VG , make an LV on the VG ,
create filesystems on the LV and /boot, mount the LV /mnt/new-root ,
mkdir /mnt/new-root/boot and mount here the /boot partition
trasnfer your installation to /mnt/new-root:
find . -xdev | cpio -pm /mnt/new-root
edit /mnt/new-root/etc/fstab to match the LV as / and ad an entry for /boot
and pass to lilo root=/dev/[your VG]/[your / LV]
it should be working
edit lilo.conf and reinstall lilo or grub ( i'm not shure that lilo can
boot from the end of 32Gb drive)
reboot once more if everything is OK
you can make a PV from your old / and ad it to the VG
that should be it
about the FS's
smth important ( may be) as far i know only Reiserfs could be shrinked ,
you can only grow XFS and JFS you can not make them smaller
i really like XFS,and not that much the others
i had some crashes and with reiserfs i have some file entries which are
reported to exist ,but they can not be stated when i try to delete them
or to see them
i have not much expiriance with JFS , but i'm hearing that it was not
that stable as of 1.0.3
and with XFS i found all lost files in " lost and find " and it was
pretty easy to bring them back
i mention only the journal ones becouse you are speaking about 32Gb
