 Posted: Tue Aug 03, 2004 10:48 pm Post subject: booting problems |
 |
|
this is my first time installing linux and i ran into some problems...
after the instalation I get the message :
>>Determining root device...
>>The root block device is unspecified or not detected.
Please specify a device to boot, or "shell" for a shell
boot()::
I just type /dev/hda4 , and everything runs smoothly from there on (i'm on gnome right now, using gentoo), but still, it's kind of a pain needing to type that every time i reboot onto gentoo
i have a single HD, one partition using WinXP (hda1), boot partition is hda2, swap is hda3, and root is hda4, using ReiserFS
here is my fstab :
| Code: | /dev/hda2 /boot ext2 noauto,noatime 1 1
/dev/hda4 / ReiserFS noatime 0 0
/dev/hda3 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0 |
and my lilo.conf :
| Code: |
boot = /dev/hda
map = /boot/.map
install = /boot/boot-menu.b
menu-scheme=Wb
prompt
delay = 50
vga = normal
default=Gentoo
#
# Linux bootable partition config begins
#
image=/boot/kernel-2.6.7-gentoo-r11
#root=/dev/hda4
initrd=/boot/initrd-2.6.7-gentoo-r11
label=Gentoo
append="root=/dev/ram0 realroot=/dev/hda4 init=linuxrc"
|
the root=/dev/hda4 line was uncomented... i tried to comment it just to see how it would turn out... same result
any1 has any ideas?
thx =)

Your lilo.conf should look like this:
| Quote: |
boot = /dev/hda
map = /boot/.map
install = /boot/boot-menu.b
menu-scheme=Wb
prompt
delay = 50
vga = normal
default=Gentoo
#
# Linux bootable partition config begins
#
image=/boot/kernel-2.6.7-gentoo-r11
label=Gentoo
root=/dev/ram0
initrd=/boot/initrd-2.6.7-gentoo-r11
append="real_root=/dev/hda4 init=linuxrc" |
I don't see anything else wrong with your configs otherwise 
The above assumes you were using genkernel to compile your
kernel btw... if you compiled manually the config would be different...
Also, I strongly recommend passing the 'read-only' call to Lilo... but
it's up to you... |

Change that line to: | Code: | | /dev/hda4 / reiserfs noatime 0 0 |
Mount does not recognize ReiserFS.

I am having a similar problem...have searched repeatedly in the forums and have not found an answer that works for more than 1 person. This appears to be a serious bug in something, I don't know what. I have everything necessary compiled in the kernel, my lilo.conf is correct, my fstab has reiserfs instead of ReiserFS, etc, etc. I'm using gentoo-dev-sources and the same kernel version as MyrddinEmrys.
Has anybody figured out a real solution?

It's just a guess, but does init=linuxrc to init=/linuxrc help?

I used lilo too in my first installation. My lilo.conf was as follow (gentoo-sources, genkernel and boot+root all together in one partition ext3):
| Code: |
# Gentoo bootable partition config begins
image=/boot/kernel-2.4.26-gentoo-r6
label=Gentoo
read-only
root=/dev/ram0
append="init=/linuxrc real_root=/dev/hda1 ramdisk=8192"
initrd=/boot/initrd-2.4.26-gentoo-r6
# Gentoo bootable partition config ends
|
It was work, but few later I changed to grub and works too.
Did you tried grub?

I have just realized that no one have mention if they have run /sbin/lilo after any changes to the /etc/lilo.conf file. It must be in another thread that I remember reading the OP saying he/she did.
Anyway, make sure you run /sbin/lilo after any changes you have made in your lilo.conf and/or you have recompile your kernel. Sounds to me that's your problem.
Note: If that is your problem, please remember to make sure your lilo.conf is as close to the handbook's example as possible before you run /sbin/lilo. Because you have made so many changes testing it, you might have broken the configuration and get an unbootable box if you just blindly run /sbin/lilo.

okey here is the sulotion, this is an older config for lilo but it works for me
ive changed this config | Code: |
boot=/dev/hda
prompt
timeout=50
default=Gentoo
vga=788
image=/boot/kernel-2.6.7-gentoo-r11
Label=gentoo
read-only
root=/dev/ram0 (the number)
append="init=/linuxrc ramdisk=8192 real_root=/dev/hdb3"
initrd=/boot/initrd-2.6.7-gentoo-r11
|
to this :
| Code: |
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
lba32
default=Gentoo
vga=788 (option !)
image=/boot/kernel-2.6.7-gentoo-r11
Label=gentoo
root=/dev/hdb3
read-only
initrd=/boot/initrd-2.6.7-gentoo-r11
append="root=/dev/hdb3 init=/linuxrc"

|
|
Hello all,
I just finished my first complete install of Gentoo.
I'm having the same problem, except I'm using grub.
Anyone have any idea on what parameters to change in grub to fix this issue? Right now, my grub.conf file looks like:
=====
default 1
timeout 11
splashimage=(hd0,2)/grub/splash.xpm.gz
title=Gentoo Linux 2.4.26
root (hd0,2)
kernel /kernel-2.4.26 root =/dev/ram0 init=/linuxrc ramdisk=8192 vga=791
real_root=/dev/hde3
initrd initrd-2.4.26
title=Windows XP
root (hd0,0)
chainloader +1
=====
I did the stage3 and genkernel install. I have my hard drive set up:
hde1=Windows XP, NTFS
hde2=swap
hde3=/, ext3
I didn't make an extra boot partition because I figured I was going to install the boot loader into the MBR on hde1. Could this be causeing the problem?
Everything else seemd to install fine, except that I got the error posted above upon reboot.
many great thanks, for the help.

I did not make an extra boot partition too, and it is working fine. My grub.conf is like this (gentoo-sources, genkernel and boot+root all together in hda1):
| Code: | ...
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title gentoo linux 2004.1 2.4.26-gentoo-r6
root (hd0,0)
kernel /boot/kernel-2.4.26-gentoo-r6 root=/dev/ram0 real_root=/dev/hda1 init=linuxrc ramdisk=8192
initrd /boot/initrd-2.4.26-gentoo-r6
... |
What is hde3? Did you mean hda3?
When you run grub will install in the MBR of hda.

Hi, I've been having the same problems as above for quite a while now. I've already posted my information here: https://forums.gentoo.org/viewtopic.php?t=152855 (a sticky at the top of this forum). If anyone looking at this thread could offer me some clear instructions as to how to work my way through this problem that would be great.
~thanks |
