#182 Issue `closed`: SLES 11 SP2 Grub Issue¶

As requested by Gratien, I open this issue to say that I have problems with SLES 11 SP2. I tested it with different physical and virtual servers.

Grub is never able to boot. I dont really know where the problem is, but a simple call of grub-install in a chroot environment is able to fix the problem.

Mail from Kai-Olaf Pieth (22 Oct 2012):

On my SLES11 SP2 install i had to edit /etc/grub.conf because it was simply wrong.
/etc/grub.conf looked like this after regular SLES11 setup:

setup --stage2=/boot/grub/stage2 --force-lba (hd0,0) (hd0,0)
quit

grub then says:
Running "embed /boot/grub/e2fs_stage1_5 (hd0,0)"... failed (this is not fatal)

But yes, it is fatal because the system won't boot

I had to edit it like this:

setup --stage2=/boot/grub/stage2 --force-lba (hd0) (hd0,0)
quit

grub then says:
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 17 sectors are embedded.

I've seen a lot of different /etc/grub.conf's on SLES10 Systems that are not working, or not working with rear, another example:

root (hd0,0)
install --stage2=/boot/grub/stage2 /grub/stage1 (hd0,0) /grub/stage2 0x8000
(hd0,0)/grub/menu.lst
quit

Mit freundlichen Grüßen
Kai-Olaf Pieth

other problematic examples are welcome : the more info we have the better to troubleshoot

I have a similar problem actually on SLES11SP2 G7 and SLES11SP1 G8..
After recovery, I have to manually setup grub again before I reboot.

on G8:
grub
grub> device (hd0) /dev/sda
grub> root (hd0,0)
grub> setup (hd0)
quit

on G7:
grub
grub> device (hd0) /dev/cciss/c0d0
grub> root (hd0,0)
grub> setup (hd0)
quit

Rear is on USB, which is after the HD in the boot order.

The special scripts for SLES have been removed in the source tree of rear. Perhaps, it is better now? Feedback would be welcome (pls use the latest checkout from github).

@dragon299 @holgermai is this still an issue with rear-1.15?

gdha commented at 2014-05-06 07:32:¶

rear-1.16 is out and fix is included
