2.6.17-rc6 No volume groups found

2.6.17-rc6 No volume groups found

[Barry Scott]

On my HP dc7600U having patch around the MCG problem
I now get a bit further. Previous working kernel was 2.6.16
from Fedora Code 4.

I see:

Uncompressing Linux... Ok, botinh the kernel.
Red Hat nash version 4.2.15 starting
  Reading all physical volumes.  This may take a while...
  No volume groups found
  Unable to find volume group "VolGroup00"
ERROR: /bin/lvm exited abnormally with value 5 ! (pid 351)

Then a few more errors and Kernel panic

Where would the problem be?

I have this kernel working on a system with IDE disks. But the HP uses
SATA disks.

Is there SATA specific LVM code that may be missing from my build of the
kernel?

You have to rebuild the initrd to match the kernel and its modules.
As the kernel develops the initrd scripts need to change to match changes
in modules required to support the disks for the new kernel.
I've no experience with 2.6.11 to 2.6.14. We now use 2.6.21
and know a bit about how to support it on FC4.

What we did to find differences was to run later versions of Fedora Core
that support the kernel we want to use out of the box. Then we break open
the initrd and see what the differences are between the old and new initrd
files.

yes, i have rebuilt the initrd by the command: /sbin/mkinitrd
--builtin=ata_piix /boot/initrd-2.6.14.img initrd-2.6.14

how did you analysis the differences? the constent of the file is scale
of two.
