 Posted: Sat Aug 28, 2004 2:13 am Post subject: Mounting /dev/hda3 on /newroot failed |
 |
|
Just when I thought I was so close!
I've tried installing Gentoo Linux on my noname laptop. When I tried booting of the hard disk I get the following message:
| Code: | >> Mounting filesystems...
Started device management daemon v1.3.25 for /dev
>> Determining root device...
>> Mounting root...
Mount: Mounting /dev/hda3 on /newroot failed: Invalid argument
>> Could not mount specified ROOT, try again
>> The root block device is unspecified or not detected.
Please specify a device to boot, or "shell" for a shell...
boot () :: |
I can't get the system started from here. I've looked around on the forums, google and newsgroups and I've tried a number of different hacks on my grub.conf and fstab. Nothing so far has worked. I've included my fstab and grub.conf below along with the listing output of fdisk. If anyone has an idea of how I can get gentoo booted that would be great.
Thanks.
cheers,
Bruce

I realize you must be running genkernel, but you might just try changing grub.conf to read like this, just to see if it boots.
| Code: | title=Gentoo Linux 2.4.26-r9
root (hd0,0)
kernel /kernel-2.4.26-gentoo-r9 root=/dev/hda3

Thank you Count_Zero, my Gibsonian Friend!
It does indeed boot now. There are some other problems with the networking that I'll take a look at next. Should I change my grub.conf to this permanently? I also removed the line that had:
| Code: | | initrd /initrd-2.4.26-gentoo-r9 |
Is this correct as well? I don't really know much about grub, so I don't know what the consequences of removing this line are.
Thank you again for your help.
cheers,
Bruce

Oh, and I am running a kernel from genkernel.
Thanks again.

Those extra lines in grub are for fancy things that genkernel likes to do, such as bootsplash. The initrd line points toward the image that would show on the screen while the computer boots, rather than the kernel messages that scroll across the screen. It looks nice, but obviously not essential. I'm not sure what the other options do, they're not needed with a custom-compiled kernel (I've never used genkernel). If you would like to get bootsplash/gensplash working, check out this topic:
https://forums.gentoo.org/viewtopic.php?t=206778&highlight=gensplash
It's not too difficult (just 5 easy steps!), and there are lots of people willing to help you through it. Best of luck!

Thank you very much count_zero! I was about to give up on Gentoo, since I have spent DAYS just trying to get it installed and the manual expects you to be a freakin computer genius.
That section of the manual SHOULD be edited because I am seeing many people with the same problem.
Cheers,
Marty |

i was looking for some answers about a problem that i was having with grub and i came across this post.
you might have helped marty, but your answer is incorrect:
genkernel is a tool for building the kernel and the initrd image. setting up all the files for bootsplash is one of the smallest things that it does
the real_root/initrd stuff gives the kernel a small ram disk as its root file system for a short period so that it can load modules before the real root takes over |
