 Posted: Wed Dec 03, 2008 5:39 pm Post subject: Gentoo - a few problems of gentoo beginner |
 |
|
Hello  I installed Gentoo few days ago. I installed it on my removable disk (2.5" HD with enclosure; connected by USB). First i had problem with run my linux. Everytime when i tried to do that my kernel said | Code: | VFS: Cannot open root device "sda3" or unknown-block(2,0)
Please appen a correct "root=" boot option; heare are available partitions |
and then | Code: | | Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) |
On other forum someone suggest me to use initrd compiled by genkernel with --slowusb option. I did it and it solved part of my problem. Now when i run my linux i gott message that linux couldn't mount main filesystem and ask me to type root directory. When i do that my linux boot properly.
And here is first question: What can i do with that? I don't want to type "/dev/sda3" every time when i run my linux.
Here is my grub.conf file:
| Code: | # This is a sample grub.conf for use with Genkernel, per the Gentoo handbook
# http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=10#doc_chap2
# If you are not using Genkernel and you need help creating this file, you
# should consult the handbook. Alternatively, consult the grub.conf.sample that
# is included with the Grub documentation.
default 0
timeout 60
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo Linux 2.6.26-r3
root (hd0,0)
kernel /boot/kernel-2.6.26-gentoo-r3 root=/dev/sda3 real_root=/dev/sda3
initrd /boot/initrd-2.6.26-gentoo-r3
# vim:ft=conf:
|
Second problem is when i try to use network. I don't have internet on my linux. i tried to use net-config but I don't even have it. When i try to use ifconfig eth0 i got message that informs me that linux couldn't find device. when i just type i get | Code: | lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
|
And here is second question: What can i do about that? What can i solve it?
And the last thing. I think that i don't have mice in my linux. Sometimes when you don't use your computer, console screen just goes black and still like that untill you move the mice or press some button (that's what i had in live cd). In my linux if i move mice nothing happens. Does it mean i don't have configured mice?
PS. Sorry for my english but i'm in england from 5 months and i still don't sprak fluently. I hope that you understand my problems

Welcome ;]
1. Post your fstab ('cat /etc/fstab')
2. Try 'ifconfig -a'. What network card do you have?
3. To have mouse in the console you need to 'emerge -va gpm' and then '/etc/init.d/gpm start' (this will start the gpm daemon which will give you support for mouse in the VTs (console). If you want it to start automatically on boot do 'rc-update add gpm default' (this will add gpm to your default runlevel).
EDIT:
If I guess correctly who you are then polish is your native language. Here is a guide for gpm in polish:
http://www.gentoo.org/doc/pl/gpm.xml (although what I posted above should be enough nowadays.
Browse through these guides - I'm sure some of them will be usefull:
http://www.gentoo.org/doc/pl/list.xml?desc=1

root=/dev/sda3 should be root=/dev/ram0 if you're loading an initial ramfs... whats on the internal drive anyway?

| I'll be watching this thread, as I'm interested in how will it end. For me it ended as: throw away initramfs and throw me into kernel reality. Perhaps, is too much for OP, but as I believe, there is no really good alternative in gentoo. Correct me, if you think, I'm wrong. Last time when I tried genkernel, I really did not want to do things manually... |

| Definitely your own kernel is the way to go - and one can always use Pappy's seeds as a nice starting point (never tried but heard only good of them). |

Bp44,
Your problem with having linux on a USB drive is that linux normally mounts root before USB has been started.
Thats an issue if you need USB to mount your root.
The solution is to add rootdelay=15 to your kernel line in grub.conf
This delays the kernel mounting root for 15 seconds, meanwhile USB is started and everything works as expected.
Values from 7 to 30 are reported to work.

thats likely not a font issue, but rather the minimal CD runs in framebuffer mode. Add a vesa framebuffer in your kernel config, enable framebuffer console support, and add vga=791 to your kernel params (for 1024x768... vga=795 for 1280x1024). For the network issue, make sure you have a via Rhine driver compile in or as a module (if the later, do an lsmod after you've booted and ensure that you have the via rhine module loaded "lsmod | grep rhine" |

What can i do with that? |
Here's where I'm starting to get on sketchy ground. I've written linux kernel modules before but always used the kernel's build scripts to build them so that all needed linking and symbols are present. You should probably do the same as there is obviously some stuff getting left out in the above that it can't find. |

just go into /usr/src/linux/, type make menuconfig, select the rhine module, save the config when you exit, and the type "mount /boot && make && make modules_install &&, make install", point grub to it, and you should be good |

once you are in menuconfig, go to device drivers -> network devices -> 100M Ethernet -> Rhine
or something very similar to that (going off memory here) |

Hmm i compiled it as a module and i added it to /etc/modules.autoload.d/kernel-2.6 but when i run my kernel it says that module couldon't be loaded. Module is in /lib/modules/2.6.26-kernel/kernel/net/
Module file ends with .ko

Bp44,
run dmesg - that will show why the module could not be loaded.
You can modprobe via-rhine just before you run dmesg so yu get the error right at the end.
