[linux-lvm] Unable to boot using LVM for "/"

[Les Hazelton <seawolf@attglobal.net>]

I have been attempting to move my root partition to a logical volume and
eliminate the current normal partition.  No luck.  I have read the
lvmcreate_initrd man page found at 

http://linux.msede.com/lvm/man/man2html.cgi?lvmcreate_initrd:8

and followed those instructions but it doesn't work for me. I have tried
two different versions of lilo (lilo-0.21.5.1-4mdk and the 0.21.6
binaries from the lilo site) and get the same result from both.

If I use grub with the menu.lst shown below I can boot the entry for
linux-2 and the system runs correctly. Neither of the other two entries
will boot correctly. The /dev/hda9 is the real partition I am attempting
to eliminate.  If I try to boot the first, linux, entry it gets a kernel
panic because it can't locate init. The third entry produces a kernel
panic because it can't mound device 0:0

----------------------------------------------------------

When the system is booted from the linux-2 entry it produces the
following.  Notice the rdev and "df -h" show clearly different views of
where the root partition is sourced.
----------------------------------------------------------
[root@farpt1 /root]# df -h

[root@farpt1 /root]# rdev

------------------------------------------------------------

My lilo.conf resides in the /boot partition which is an ext2fs on
/dev/hda5. It is listed below.  When I install lilo and try to boot the
system It comes up but it is using /dev/hda6 for the root partition and
that belongs to my test copy of LM v7.2 and should have nothing to do
with this system. 

The one thing that is clearly different is that the lvmcreate_initrd man
page references ext2fe file systems and I am using reiserfs for all
except the /boot on /dev/hda5. Can anyone see what I am doing wrong and
get me turned around?  I would sure appreciate the help.
