 |
|
I recently rebooted my computer.
Now it won't start because of a failure.
The problem I have is very simular to this thread :
https://forums.gentoo.org/viewtopic-t-403485.html
| Code: |
Starting devfsd
sbin/rc:line 313:/sbin/devfsd No such file or directory
Could not start udev
not avail
Failed to open device /dev/hda3/
|
That's the error I get.
How I did it, I don't know. Maybe something went wrong during an emerge -uDv world and has overwritten a config file.
The hard disk is ok, I can access everything when I use a livecd.
I have heard of udev, but I don't know if I use it.It's possible.The same with devfs.About a year ago,I have followed the gentoo installation manual and since then I changed nothing that's related with /dev/
I tried to change, /etc/conf.d/rc to udev and devfs, but nothing helped.
Some help would be nice.
How can I re-emerge udev when I can only access my root partition in read only?
The live cd I use is a differen linux distro.

If i am not mistakeing kernel no longer uses devfs, only udev...
So you should use udev  Have you recompiled your kernel reacentlly?
Some help with udev: http://www.gentoo.org/doc/en/udev-guide.xml
Possibly, you coulduse gentoo livecd and chroot into your installation, configure the system to use udev and then try to boot again...
( emerge sync ; emerge & configure udev; compile fresh kernel and so on )

For the people with the same error, you can follow these steps:
- boot with livecd
- mkdir /mnt/gentoo
- mount /dev/hda3 (root part) /mnt/gentoo
- mount /dev/hda1 /mnt/gentoo/boot/
- mount -t proc none /mnt/gentoo/proc
- chroot /mnt/gentoo /usr/bash/
- env-update
- source /etc/profile
- ntpdate with ntpserver
- emerge --sync
- emerge udev coldplug hotplug
- rc-update -a coldplug boot
- cd /usr/src/linux
- make menuconfig
Then I follow http://www.gentoo.org/doc/en/udev-guide.xml
(kernel part)
- make && make modules_install
- cp arch/i386/boot/bzImage /boot/kernel-2.6.11-gentoo-r3
-reboot
And It's working again.
Thx for ur reply rdk. |
