[linux-lvm] "I have no root and I want to scream"



Howdy folks,

I'm one step closer to having a working LVM system then I was
yesterday. I've managed to create my volume group and all the
logical volumes that I want too, and I've got the operating
system installed on them -- once I mounted them to the
appropriate places the Debian boot/setup program worked as
expected with a non-LVM setup. And I've got LILO setup per
the LVM-on-root howto. One difference, when I try to specify
/dev/vg00/lv03 as a boot device, I get an error from lilo
saying that "/dev/vg00/lv03 isn't a number", so I specified
it as 5803 like you do with rdev.

When I boot the ramdisk gets loaded, and both vgscan and
vgchange seem to work as expected, but when it comes time
to "fall through" to the real root device, I get one of the
following errors:

If I specified root as "5803" at the lilo command prompt,
which I intend to use the thrid LV as my root volume, then
when it falls through it says that it can't mount device
58:03. It should be able to, there is a valid ext2 filesystem
on it, and ext2 is compiled into the kernel -- not a module.

If I specified root as "/dev/vg00/lv03" at the lilo command
prompt, then when it falls through I get the message
"Kernel Panic: I have no root and I want to scream"

I can still get in via the debian boot disk and make changes
to the lilo/LVM setup. Anyone know what changes I need to make?

My kernel is stock 2.4.3 + 0.9.1-Beta6 kernel patches.
My tools are stock 0.9.1-Beta6
Everything else is whats in stock Debian 2.2 -- I can look up
 versions of specific things if need be.

Thanks,
Christopher
