 Posted: Thu Sep 23, 2010 1:52 am Post subject: Gentoo wont boot after kernel upgrade (grub problem) |
 |
|
Hi all,
I've got a weird problem with my gentooserver after upgrading my kernel with genkernel. For some reason it wont boot anymore. When i try to boot it says:
| Code: |
Grub loading Stage1.5
Grub loading, please wait...
|
Then grub hangs up indefinetely.
So, i booted from a gentoo liveCD, setted up my network and sshd and logged into it. After that:
| Code: |
swapon /dev/sda2
mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
cp -L /etc/resolv.conf /mnt/gentoo/etc/resolv.conf
|
then chroot to the system"
| Code: |
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1"
|
After that i updated /etc/mtab sinds Grub needs this:
| Code: |
cp /proc/mounts /etc/mtab
|
My partitiontable:
| Code: |
(chroot) livecd / # fdisk -l
Disk /dev/sda: 33.8 GB, 33820286976 bytes
255 heads, 63 sectors/track, 4111 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Disk identifier: 0x00000000
Disk /dev/sdb doesn't contain a valid partition table
(chroot) livecd / #
|
After that i tried reinstalling Grub:
| Code: |
(chroot) livecd grub # grub-install /dev/sda
Unknown partition table signature
Unknown partition table signature
Unknown partition table signature
Unknown partition table signature
Unknown partition table signature
Unknown partition table signature

Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.
(fd0) /dev/fd0
(hd0) /dev/sda
(hd1) /dev/sdb
(chroot) livecd grub #
|
When i did a "ls -al /boot/grub" i noticed there was not grub.conf nor a menu.lst so i tried installing it by hand:
(/boot is on sda1)
| Code: | grub
grub> root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 17 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+17 p (hd0,0)/boot/grub/stage2
/boot/grub/menu.lst"... succeeded
Done.
grub> quit |
but still no menu.lst nor grub.conf. So i made my own:
menu.lst:
| Code: |
default 0
timeout 15
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo Linux 2.6.34-gentoo-r6
root (hd0,0)
kernel /boot/kernel-2.6.34-gentoo-r6 root=/dev/sda3
initrd /boot/initramfs-genkernel-x86-2.6.34-gentoo-r6
|
after that:
ln -s menu.lst grub.conf
and rebooted but still the same problem.
I also used a clean CFLAG and recompiled Grub with:
| Code: | | CFLAGS="-O2 -march=i686 -fomit-frame-pointer -pipe" emerge grub |
as stated here: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=10#grub-install-auto
After that i ofc installed grub again with:
| Code: | | grub-install --no-floppy /dev/sda |
Still the same problem...
Here is the content of my /boot:
| Code: |
(chroot) livecd / # ls -l /boot

Hi, did you try to
before mounting it when you chrooted ?
Maybe its a file system corruption ? |

Looks all ok
btw i also wiped my MBR with:

Hi EzMe.
It seems that the root cause was that the automatism of genkernel, if it was started with --bootloader=grub (or it is activated into genkernel.conf) shreddered your grub / grub.conf.
You don't submit your fstab. Did it mount your /boot partition everytime?
Otherwise you have to mount it manually before starting genkernel with the --bootloader=grub option.
You also did not post the content of your /boot/grub directory, so i have to shot in the dark a little.
Beside of this it seems to me that you have done nearly everthing right, aside one little thing, not shure if it's responsible for your trouble.
You did this:
| Quote: | | ln -s menu.lst grub.conf |
which is not correct or not default for gentoo (but default for most of the others distros out there, but in my opinion only gentoo did it right and consistent to the other conf. schemes )
The grub.conf is the real file, and the menu.lst is the symbolic link which points to it, so you have to reverse it:
| Code: |
ln -s grub.conf menu.lst
|
If you want try a minimal solution, change only this, and repeat the grub-setup in the grub-shell in the same way you have done, and retry.
If this doesn't work for you, do exactly this, and i'm pretty shure it will work for you:
Delete all files into your /boot direytory except for the kernels, System.map and initramfs you will need further.
Delete all files into your /boot/grub directory except the grub.conf and the menu.lst
Really all others, all your old grub.old directories, and especially the boot -> . links and so on.
You can reinstall grub easier without chrooting into your system using this way:
Boot your Live-CD and then do excactly this don't append /boot to the mentioned path this time, cause we only mount the target partition for your grub:
| Code: |
mount /dev/sda1 /mnt/gentoo
grub-install --root-directory=/mnt/gentoo /dev/sda1
|
then do again what you did
| Code: |
grub
grub> root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 17 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+17 p (hd0,0)/boot/grub/stage2
/boot/grub/menu.lst"... succeeded
Done.
grub> quit
|
Reboot / retry
Eventually you have to correct your kernel boot line, if it is not fully right (real_root...)
but your main problem should be fixed then.
Much success, Andy.[/quote]

Im pretty sure i mounted my /boot partition before compiling my kernel. I compiled it like this btw:
| Code: | | genkernel --bootloader=grub all |

Good notice!  I tried it the other way around but that didn;t seem to fix my problem. So im gonna try your other option.

But that brought me at a GrubCLI. After checking where things went wrong, i noticed that the grub-installer made a /boot dir in the /boot dir where it could not find the kernel files ofc.

Im gonna do some more puzzling Thanks for the help sofar! |

Hi EzMe,
i'm still missing your fstab, which grub version and filesystem you are using for sda1 (i guess ext2, but what does you enter into fstab, which is not relevant at boot time). Some more ideas to help resolving your problems.
1. - what happens if you comment out the splashimage line into your grub.conf, does it work then, cause the picture file yould be broken?
2. - how big is your sda1 (boot) partition, and how old is your bios. Old bioses has a capacity limitation, and could boot only from (8/20/who don't know)GB big first partions. (i guess your boot partition is 40MB big, so this should not be the problem here)
3. - eventually you have to reformat your boot partion only, and reinstall grub as you did, copy back your saved kernel files and grub.conf and menu.lst before.
No more ideas this time...
So i look forward to here good news from you

if you can't handle the /boot partition and the /boot directory (we're brainless sometimes), gentoo won't kill you from doing that
umount /boot
echo "nothere" > /boot/DONT_USE_ME
lol, i will award the most lame tip with that one |

i'm still missing your fstab, which grub version and filesystem you are using for sda1 (i guess ext2, but what does you enter into fstab, which is not relevant at boot time). |
Sorry bout that Here we go:
| Code: | (chroot) livecd / # grub --version
grub (GNU GRUB 0.97) |
Btw.. i also tried booting from grub2. The kernel seemed to boot but it gave me another error:
| Code: | ::Activating mdev
::Determing root device
line 513: blkid: not found
Could not find the root block device in UUID=ablahblahblah
::Please specify another value or: press Enter for the same, type "shell" for a shell, or "q" to skip. |
I checked with blkid to make sure it was using the right ID but still it gave me this error. Could that imply that there aint an error in the boot partition but in hda3?

All looks good if you ask me.

1. - what happens if you comment out the splashimage line into your grub.conf, does it work then, cause the picture file yould be broken?

I tried that also.. didn't work

3. - eventually you have to reformat your boot partion only, and reinstall grub as you did, copy back your saved kernel files and grub.conf and menu.lst before.

Yups, I guess so. Let's see how far we get
I loled at krinn Some mistakes can be so small there are hardly noticed |

Yepp,
that's why i want to take a look at fstab.
EzMe, please correct all dev/hda lines to sda, and the sda line to sdb ift this is your second hard drive with /home/big mount point and retry!
Regards, Andy.

Hmm.. you guys allmost gave me hope
I changed my /etc/fstab like this:
| Code: |
/dev/sda1 /boot ext2 defaults,noatime 1 2
/dev/sda2 none swap swap 0 0
/dev/sda3 / ext3 noatime 0 1
/dev/cdrom /mnt/cdrom auto noauto,user 0 0
/dev/sdb /home/big auto noatime 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
proc /proc proc defaults 0 0

For your information of my drive layout. None of my boxes has a seperate boot partition, but everyone contains two different systems (one on sda1, second one on sda2) which i can boot from with its own boot loader. The both grub bootloaders are connected via chainloader. I prefer this layout for my own, that's why i'm not so experianced in using a seperate boot partition.
Nevertheless it seems wrong to me, that your sda3 contains a bootloader, cause its your root partition.
If none has a better idea, i guess you should move your needed files / system / kernels to free space on sdb. Then reformat / partitioning the whole drive to your needs, and copy back your files to the newly created directories.
Then reinstall / configure grub again.
Good luck, Andy
