A real lilo pickle
 
ok here is what I got going on,
I have a Intel server running a SMP kernel, with hardware raid.
I have started replacing my really under used servers with VM servers, so I have been imaging them and restoring them to a Virtual machine.

So on the physical box the drives were address as md0, but on my virtual machine it's going to be sd0
I basically need to edit the config file to point to sd now and not md or hd.

here is my origional /etc/lilo.conf

I was able to complete this task with another machine that was running grub, but I have not worked with lilo for a long time so I was hoping someone else might have something to sugguest?

HELP!
Thanks!

Do I need to install lilo to the new drive? sda... or did it come over with the ghost image?

AFAIK, if you use dd (and ghost probably use that method), so if you use dd
and do not skipe the first bytes then the image includes the MBR,
hence it inclus grub/lilo/whatever provided your bootloader is on the MBR (as opposed to being chainloaded)

Not sure how to help with that

Well I got it booting to it kinda, I used a rescue cd to chroot into the enviroment and install lilo to it again.
But now I am getting this,

"Kernel panic: No init found. Try passing init= option to kernel"

init seems to be living in /sbin

Here is my lilo.conf

If you have raid this sounds wrong

legacyboy 06-05-2006 10:32 AM

I did have raid, I imaged a raid machine and moved it to a non-raid machine,

Emmanuel_uk 06-05-2006 02:25 PM

Ok, how about you ghost/copy the whole thing (provided it was raid 1)
and you reinstall grub rather than lilo?
I have never tried to rebuild a raid 1, let alone make one disk of a raid 1 become a single HD.
I think grub rather than lilo because it is more flexible.

Am sorry no other thoughts for now
