Hello,

Nice Post. I"m curious. Would this method work with Debian 5.0 Lenny? I am searching for a way to go from a grs to std kernel on lenny.

Thanks!

Hi,
thank you very much for your tutorial. I followed all the steps you described, my server still boots but unfortunately it boots still the ovh kernel.
Any clue why my system does not recognize the new kernel? (I had some error messages during the kernel-install that said that /proc/modules was not found).

Thank you for your help and sorry for my English,
Martin

P.S: You can also write me on twitter if you want to: @murphy2

Thank you for this post. As an alternative you shouldn't get any error message if you create the /boot/grub directory before launching the 'sudo apt-get install linux-server grub'.

My kimsufi machine runs Ubuntu 9.04 and has its /boot directory on RAID-1 partition (/dev/md1). After running 'setup (hd0)' I realized (too late) that /boot/grub/menu.lst was created with:

kernel /boot/vmlinuz-2.6.28-17-server root=/dev/md1 ro quiet splash (WRONG)

which doesn't work because the grub doesn't know about the raid at boot time. I corrected via the Netboot console with root=/dev/sda1:

kernel /boot/vmlinuz-2.6.28-17-server root=/dev/sda1 ro quiet splash

Also, since this is a mirrored raid, I wanted to be able to automatically boot from /dev/sdb1 should the first drive fail. Here's are the instructions to follow in the grub shell (booth partitions /dev/sdba1 and /dev/sdba2 must be synchronized):

> device (hd0) /dev/sdb
> root (hd0,0)
> setup (hd0)
> quit

and reboot!

Eric.

P.S. Each time my grub setup (hd0) returned this error:
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"… failed (this is not fatal)
Running "embed /boot/grub/e2fs_stage1_5 (hd0,0)"… failed (this is not fatal)
but that didn't prevent the server from rebooting via the grub.

just tried this – seems to have gone through all the steps fine, but it's still using the old kernel … any pointers?
