 Posted: Tue Jan 27, 2004 11:24 pm Post subject: Problems with GRUB during install |
 |
|
Hello folks.
I'm a new user, but not that new to gentoo.
I've installed gentoo from scratch two times before, but always had someone over my shoulder to help me out... this time I went for it by myself, and can't seem to get the bootloader to work.
I did as instructed and "emerge --usepkg grub".
Followed all the instructions.
I used genkernel, so my grub.conf looks like this:
--------------------------------------------------
default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.4.22
root (hd0,0)
kernel (hd0,0)/kernel-2.4.22 root=/dev/ram0 init=/linuxrc real_root=/dev/hda3
initrd (hd0,0)/initrd-2.4.22
--------------------------------------------------
Now, when I rebooted and got to the bootloader, I select "Gentoo Linux 2.4.22" and I get:
--------------------------------------------------
Booting 'Gentoo Linux 2.4.22'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel (hd0,0)/kernel-2.4.22 root=/dev/ram0 init=/linuxrc real_root=/dev/hda3
Error 15: File not found
Press any key to continue...
--------------------------------------------------
Then it loops back to the grub splash.
What have I done wrong??? Any and all help is appreciated. |

| Well, maybe you already did this and didn't say, but the first step is to verifiy that your kernel really is named kernel-2.4.22 and is in hda1 |

I used the latest vanilla-sources, and verified that it was kernel-2.4.22...
And seeing that I followed the install documentation, except that I used cfdisk instead of fdisk, I don't see why the kernel wouldn't be located in hda1.
How can I verify that? And IF it's somewhere else (it would only be hda3, if it was anywhere else) what do I change?
My partitioning:
/dev/hda1 Linux ext2 64 M
/dev/hda2 Linux swap 512M
/dev/hda3 Linux reiserfs~39Gb |

I wasn't asking what kernel version it is, but rather what the file name is. mount the /boot partition if it isn't already, then type
then post the output here. |

Okay, here you go:
ls -l /boot/
total 31
lrwxrwxrwx 1 root root 1 Jul 24 2003 boot -> .
-rw-r--r-- 1 root root 9728 Jul 23 2003 boot-bmp.b
-rw-r--r-- 1 root root 9216 Jul 23 2003 boot-menu.b
-rw-r--r-- 1 root root 7680 Jul 23 2003 boot-text.b
lrwxrwxrwx 1 root root 11 Jul 24 2003 boot.b -> boot-menu.b
-rw-r--r-- 1 root root 908 Jul 23 2003 chain.b
drwxr-xr-x 2 root root 1024 Jul 23 2003 grub
-rw-r--r-- 1 root root 512 Jul 23 2003 mbr.b
-rw-r--r-- 1 root root 840 Jul 23 2003 os2_d.b
-----------------------------------------
Sorry if the formatting is crap, I'm typing this out by hand. |

Hmm, I don't see your kernel in there. Are you sure you're boot partition was mounted when you ran genkernel? Try this:
| Code: | umount /boot
ls -l /boot
|
This shouldn't list any files, but if it does, post the output again. |

I can't tell you 100% that boot was mounted when I ran genkernel... but I don't think I would have missed that. But it's looking like that, isn't it? |

I'm not sure what that entry is but try this:
| Quote: | mount /boot
cp /usr/src/linux/arch/i386/boot/bzImage /boot/kernel-2.4.22

Okay, I did that, and I get the same Error 15: File not found when I boot from grub, but the output is a little different:
-----------------------------------
Booting 'Gentoo Linux 2.4.22'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel (hd0,0)/kernel-2.4.22 root=/dev/ram0 init=/linuxrc real_root=/dev/hda3
[Linux-bzImage, setup=0x1400, size=0x118960]
initrd (hd0,0)/initrd-2.4.22
Error 15: File not found
Press any key to continue...

| Now it's not finding the initrd file. For now, comment out that line in grub.conf. If you need the initrd, then rerun genkernel |

Okay, well, that did it.
It gets through GRUB and starts to load the kernel...
BUT
Now it goes through the load process for a while and it dies at:
Kernel panic: VFS: Unable to mount root fs on 01:00
Maybe my fstab is wrong? |

It might be that, or it might be the kernel parameters
| Quote: | | root=/dev/ram0 init=/linuxrc real_root=/dev/hda3 |
I've seen this before, but I don't know what it is (for all I know, it could be that it needs the initrd to work, or maybe not). On my system, it simply says root=/dev/hda3. Changing that may solve your problem, but remember I'm not saying yours is wrong as is, I just don't know what it does differently than mine. Unless someone else who knows steps in, my sugestion would be to follow these steps:
1. make sure you fstab is correct. If it is, then
2. change the kernel parameters so it only says root=/dev/hda3. If this does make the computer boot, then the next step is to work on getting your original kernel parameters to work correctly. I'll try to do a little bit of research about that.
ps I'm leaving work right now, so I might not be able to post again till tonight. |

thanks for the help, I think I'm just going to cut my losses and start over again. |

Wait, don't do that! I'm sure we're almost there. If you haven't done anything yet, then just wait a bit and I'll get back with more information.
<EDIT>
Okay, if you havent started over already, scratch my above post. I didn't know this before because I don't use genkernel but
| Quote: | | root=/dev/ram0 init=/linuxrc real_root=/dev/hda3 |
is what you use if you are using genkernel, so leave that as is. I'm about 99.9 % sure that the reason it cant mount the root filesystem is because I had you comment out the initrd line to prevent the file not found error. This is what I should have had you do instead: rerun genkernel (with boot partition mounted, ofcourse). This will place a new kernel and an initrd in you're boot partition. Afterwards, verifiy that they really are in the /boot partition, and make sure that the filenames are the same as in your grub.conf. Also uncomment the initrd line. I'm pretty sure that this will solve your problem.

i skimmed the posts and don't thinkt his was mentioned.. do an ls /boot and take a look at the filename of you rkernel.. you sure youhave the kernel name correct?
bzImage = kernel name

Okay, going to give that a shot, and I'll get back to you when genkernel is done. |

oh, btw:
I don't "mount /boot"
I: mount /dev/hda1 /mnt/gentoo/boot
That doesn't make a difference right? OR am I just that stupid? |

| I'm sorry, I didn't even consider that. What you are doing is correct if you booted into the livecd. Once your system is working, then you will do "mount /boot" Thanks for thinking for yourself instead of automatically typing exactly what I do. |

Like I said at the beginning, I'm not a total n00b with this stuff... and I will say, I've learned a LOT this time around doing it all myself.
genkernel is compiling as we speak. |

Okay, here's another Q:
when genkernel is finished, I'm assuming I need to re-emerge hotplug and whatever other modules I emerged after genkernel finished???
(genkernel's still running, btw) |

Okay!
We ARE getting somewhere....
I fixed the kernel panic...
I get to the following:
---------------
Gentoo initrd startup...
STEP 1: Command-line parsing
STEP 2: Module loading
---- Scanning for sbp2...no such module found
STEP 3: Mounting necessary filesystems per boot options
Started device management daemon v1.3.25 for /dev
STEP 4: Determining root device
STEP 4a: Mounting root
mount: Mounting /dev/hda3 on /newroot failed: Invalid argument
Could not mount specified ROOT, try again
Root block device unspecified or not detected.
Please specify a device to boot, or "shell" for a shell.
:_
-----------------------------
It just flashes a prompt.
I'm going to post my fstab here momentarily. |
