Issues Booting After Install [SOLVED]

Message

Nemein · Post by **Nemein** » Tue Feb 15, 2005 2:08 pm

Lo all,

I'm having a no boot issue with my recently installed Gentoo. I used the Stage 1 on Stage 3 NPTL install method and everything was doing fine until I rebooted after completely finishing the install. I'll print out the errors once I can get back control of my computer. My computer starts the boot and then fails accusing that my /root partition isn't mounted and a command of the likes of rc_splash is not found (plus two other things I can't remember off the top of my head). Once again, I will be more specific once I get to use that comp again (currently in use for Windows). Anyways, here's a bit of the information about my comp that might help somehow:

/dev/hda1 - Windows XP - NTFS - 30 GB
/dev/hda2 - Boot - ext2 - 32 MB
/dev/hda3 - Swap - sw - 512 MB
/dev/hda4 - Root - ReiserFS - 9.4 GB

Using GCC 3.4.3.20050110. Amazingly enough, I was able to get a full install running a few days ago using a testing branch ONLY system (with it's inherent instabilities) but it seems I just can't get this install to function properly. Any help would be appreciated. I'll post fstab and grub.conf asap. Thanks.

...so post fstab and grub.conf

Here goes:

The errors I get:

Code: Select all

Fstab:

And finally fdisk -l:

Hope this helps. Thanks in advance.

I'm having the same problem after following the same HOWTO.

My fstab

Code: Select all

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda1		/boot		ext2		noauto,noatime		1 1
/dev/sda3		/		reiserfs	noatime			0 0
/dev/sda2		none		swap		sw			0 0
/dev/sda5		/opt		reiserfs	noatime			0 0
/dev/sda6		/var		reiserfs	noatime			0 0
/dev/sda7		/tmp		reiserfs	noatime			0 0
/dev/sdb1		/home		reiserfs	noatime			0 0
/dev/sdb2		/usr		reiserfs	noatime			0 0
/dev/cdroms/cdrom0	/mnt/cdrom	iso9660		user,noauto,ro,exec	0 0

# NOTE: The next line is critical for boot!
none			/proc		proc		defaults		0 0

none			/dev/shm	tmpfs		defaults		0 0

and my grub.conf

Code: Select all

# Boot automatically after 30 secs.
timeout 30

# By default, boot the first entry.
default 0

# Fallback to the second entry.
fallback 1

# Use Gentoo splash image
splashimage=(hd0,0)/grub/gentoo.xpm.gz

# For booting GNU/Linux
title  Gentoo Linux 2.6.10 - gentoo-dev-sources-r6
root (hd0,0)
kernel /kernel-2.6.10-gentoo-r6 root=/dev/sda3

# For booting GNU/Linux
title  Gentoo Linux 2.6.10 - gentoo-dev-sources-r6, 1600x1200
root (hd0,0)
kernel /kernel-2.6.10-gentoo-r6 root=/dev/sda3 video=vesafb:ywrap,pmipal,1600x1200-24@85 splash-verbose,theme:emergence
initrd (hd0,0)/fbsplash-emergence-1600x1200

If it matters, I try booting the first grub entry.

One thing about the howto that seems suspicious to me regards udev. There is only one
mention of configuration for the file /etc/conf.d/rc. Other than that, no configuration. I haven't
used udev before so I don't know if the lack of configuration could be related to this problem.

Indeed this is an udev issue. For now I am getting around it
by rebuilding the kernel with devfs, and reversing the suggestions
for /etc/conf.d/rc.

I also removed some of the commands from the default runlevel
(coldplug hotplug xinetd acpid), but I'm not sure if that played a
role in getting the system to boot.

For reference my system is a dell precision 670, dual xeon, with
SATA drives.

Would any of the more experienced Gentoo users be willing to give me some advice as to how I can resolve my issue? I'd greatly appreciate your help. All of the pertinent information is posted above (my fstab, fdisk -l and the errors I get as I load gentoo). Thank you in advance.

Apparently, I came to my senses and checked my kernel and rc.conf and noticed that I had no support for devfs in my kernel yet it is still needed at boot time for one of the filesystems to load correctly. Re-enabling it in the kernel and also selecting to make it auto-mount at boot in the kernel and the sub-sequent recompilation of the kernel solved the problem.

With this solution I don't believe we are using udev, but at least the
system works. I'll leave udev for another day.

I don't know if udev in its current state is a complete substitute for devfs. Anybody with more knowledge about the inner workings of Gentoo could help us clear this matter. As is currently sitting, I have both udev and devfs support on my Gentoo install.

I get the same error message when booting gentoo, after following the stage1 developers guide. I guess Ill have to enable devfs in my kernel too...

Nemein · Post by **Nemein** » Sat Feb 19, 2005 9:23 pm

I got rid of devfs after recompiling my kernel and things are as stable as ever running solely on udev. What you have to do is make sure you have /dev/null and /dev/console mounted prior to boot, which was not happening with me and seems to be the problem with you. Go to this page and scroll down to where you'll see the Missing device node files at boot section, under Known Issues. That was exactly the problem I was having and going through those steps should solve things for yah

Btw, this is the CORRECT solution for the issue with /dev/null at boot. There's no need to enable devfs
