Yup.. I forgot to run /sbin/lilo but it doesn't take.  The first error is
failed to create /dev/mapper/control and after that everything fails and it
ends up in a kernel panic.

Well I patched the lilo mdk source file myself so it's probably my fault
(didn't see anything wrong though).  I tried to get your package from
comedia.it but it's not responding, can I get it somewhere else ?

I noticed that lvm1 was loaded instead of lvm2 but when I check
update-alternatives --config lvm I see lvm2 used as default over lvm1.
Might this be causing my kernel panic (no init found).

hmmmmm..... I'm getting a different kernel panic, this time it tells me to
try and pass the init= option but I saw it managed to load the device
mapper.  Any gotchas you know of that I might be missing ?

>I using Mandrake 9.2 with mkinitrd 3.5.15.1 and a patched lilo 22.5.8
3.5.15.1?, you mean _MY_ mkinitrd and _MY_ patched lilo?
http://www.comedia.it/~bluca/cooker/lvm2
good, then i can help you

(i suppose you also installed the other stuff from there: lvm1 and lvm2
and initscripts)

>>your distro probably has an mkinitrd command, so you would need to patch
>>it to support lvm2 if it does not already.
just run mkinitrd -v -f /boot/initrd-2.4.22.img 2.4.22
(assuning it was a vanilla 2.4.22)

then you should have a block in your /etc/lilo.conf that looks like
this:
image=/boot/vmlinuz-2.4.22
        label=lvm2
        root=/dev/root/1
        initrd=/boot/initrd-2.4.22.img
        append="devfs=mount"
        read-only

>>you might also need to patch your sysinit boot script
>Could you be a little more specific regarding the sysinit boot scripts as
>it's probably the most confusing part of the process.

if you install the initscripts on my page it should just work
(note that i updated my page today)

note my patched initscripts does not care what the default alternative
for lvm is (lvm1 or lvm2) but you might, so check and change it with the
"update-alternatives --config" command if you have both rpm installed.

note2: if you want a mandrake patched kernel with support for lvm2
included go to: http://www.netikka.net/tmb/Cooker

Could you be a little more specific regarding the sysinit boot scripts as
it's probably the most confusing part of the process.

Hello all.

I've been scratching my head on this for a few days now.  I decided to to
migrate to kernel 2.6 but first I need to migrate from lvm1 to dm+lvm2
(from what I understand).  So I've allready patched a vanilla 2.4.22 kernel
with the device-mapper patch and with lvm2 support build into the kernel
and it compiled just fine. However since I'm running my root filesystem on
lvm I'm stuck on how to booth the sob.  I tried to add the a new kernel to
my lilo.conf using root=/dev/root/1 but all I get is kernel panic.  From
what I've read I nead to create an initrd image but thats where the docs
and previous posts get a little fuzzy.  So what are the next few steps for
me ?  Could someone shed some light on this because I've been googling for
a while now and I seem to be utterly stuck in the mud here :(

TIA
-Kjartan
