[Bug 440587] Re: grub2: 'error: no such partition' when trying to boot from hd0, 10

2010-01-03 Thread victor_ze 
Felix, I have the same issue. Using qemu I have installed on my 320GB 2.5 SATA 
HDD ubuntu using alternate CD (using automatic partitioning) and it boots and 
works fine under qemu.
However, if I put this 320GB HDD in soekris (embedded board) I get the same 
grub error no such partition. It looks like /boot partition gets assigned 
sda5 and it is far after LVG partition, but soekris BIOS detects 320GB HDD as 
134GB, so it seems that its BIOS fault, what could be workaround? Should I 
create partition table manually specifying /boot as first partition on the disk 
start? Why ubuntu automatic partition assigns /boot as last partition on the 
end of the disk?

Under qemu:

Please try if this still happens with my latest PPA upload:
https://launchpad.net/~fzielcke/+archive/grub-ppa/
Note that it's the experimental branch from upstream and so could contain other 
bugs.

What does it work around?
Does it do more then just hiding the out of disk error?
If so then we probable have some bug in the error handling.

The kernel out of disk error is a sign for either a bug in our
filesystem code or in the filesystem itself.
Unfortunately reiserfs is the only filesystem for which we have debug
code.
Though it could also be a BIOS bug that it reports a different disk size
then it actually has.
 
 Please confirm the funtion of the above code. Thanks.
 

I doubt this function is the problem.
And if you would have looked a few lines below where this function gets
actually called it would give you at least a hint how you can find out
for which sector number that function fails.

To get the disk dprintfs shown in rescue mode the following should work,
but it seems like the pager only works in mormal mode.
sudo -s
printf 'set pager=1\nset debug=disk'  /boot/grub/rescue.cfg
In /usr/sbin/grub-install change this line
  $grub_mkimage --output=${grubdir}/core.img 
--prefix=${prefix_drive}${relative_grubdir} $modules || exit 1
to this
  $grub_mkimage --config=${grubdir}/rescue.cfg --output=${grubdir}/core.img 
--prefix=${prefix_drive}${relative_grubdir} $modules || exit 1
and then just run it like usual.

Though because you're already familiar with compiling and modifying it
you could also replace the grub_dprintf with normal grub_printfs.

Hi, I also met the same problem. But I comment the following code to
work around it.

Package: grub-1.97.1.tar.gz

[Bug 440587] Re: grub2: 'error: no such partition' when trying to boot from hd0, 10

2009-10-09 Thread tavasti 
Older grub gives better erro message telling BIOS can't access such
partition. sda10 is not itself too far on disk, but to get address of it
grub has to walk through sda5-sda9. And apparently BIOS can't access
sda8 beginning?

I think this bug can be marked as minor, only thing to fix is give more
informative error message. If BIOS can't access it, it''s impossible to
boot from that partion. After deleting and creating logical partitions
in correct order grub works fine.
