[gentoo-amd64] Can't install Grub 0.97-r5

[alain.didierjean]

I emerged grub's last version. So stage 1, 1.5 & 2 are in /boot/grub allright.
But trying to install the new mbr gives:
grub> root (hd0,0)
 Filesystem type is ext2fs, partition type 0x83

grub> setup (hd0)
 Checking if "/boot/grub/stage1" exists... no
 Checking if "/grub/stage1" exists... no

Error 15: File not found

Of course, /boot/grub/stage1 is there.

So I'm stuck with a half installed grub and dare not reboot. I re-emerged the
last version to no avail.
Any practical advice before I re-emerge previous grub version?

There was a related issue discussed on this list recently, search the
archives for email from Duncan with subject "boot Gentoo from USB key"
dated May, 2.

I don't know if this really applies to you, in my case I had that
problem on a newly formatted (USB) drive. Newer mkfs.ext2 by default
build 256 bytes I-nodes, and these are not recognized by grub. I
re-formatted the drive using 128 bytes I-nodes (option -I to mkfs.ext2),
and it ran smoothly. The symptoms were exactly as you describe, I could
see the stage* files on the disk with ls, but grub told me Error 15.

Did you re-create the filesystem on (hd0,0) recently? If so, you'll
probably have the 256 byte I-Nodes that grub doesn't like. You can check
I-node size with dumpe2fs.

Grub 0.97.5 handles 256 inodes.
Handling 256 inodes was a major reason that 0.97.5 was written.

maybe portage does it itself but i'm not sure about this last affirmation.

  you have left the old version in use. to fully update grub not only you need to update it via portage but also you should reinstall the bootloader. maybe portage does it itself but i'm not sure about this last affirmation.
  confirm that the last affirmation is true

same here on two systems. Did a reboot to test before reinstalling grub.

I think the situation being warned about is one in which:
 a)  /boot filesystem is added or is remade as ext2/ext3 with inode_size=256
and
b)  the failure to reinstall grub has left the old stages 1, (1.5), and 2 in 
place in the MBR which will fail to handle the inode_size=256 file system.

Is /boot mounted?

Grub has made a guess as to which drive to call hd0. Perhaps it guessed 
wrong?
running:
grub
find /boot/grub/stage1
will tell where grub sees the specified file


Unrelated thought:
if you had an inode_size problem the error would be:

grub> setup (hd1)
 Checking if "/boot/grub/stage1" exists... no
 Checking if "/grub/stage1" exists... no

Error 2: Bad file or directory type

Stupid me. I have added an IDE disk since grub last update...
And now, my sda1 /boot partition is seen as (hd1).
The find command of grub solved it for me. I didn't know it before list's help
I guess I should RTFM. Thanks for the help, guys.
