Bug#566735: grub-pc: Unable to boot from LVM, "error: no such disk".

[David L. Anselmi]

Package: grub-pc
Version: 1.98~20100101-1
Severity: important

Hi,

I'm unable to get grub-pc to boot.  When installed it says this on boot:

error: no such disk
Entering rescue mode
error: no such disk

and gives me a rescue prompt.  By running grub-install --modules=minicmd I could
see this:

lsmod:
lvm
part_msdos
ext2
fshelp
biosdisk
minicmd

ls:
(hd0) (hd0,2) (hd0,1) (fd0)

So it looks like grub can't see the LVM partitions.

I have a similar system that works fine with grub2.  What can I do to figure out
why LVM doesn't show up?

Thanks!
Dave
