[SOLVED] No sd* in /dev...

BeaverusIV · 10-07-2010, 03:28 AM

When I boot my machine it fails at the disk check so asks me to remount and check. I can run

Code:

mount -no remount,rw /

fine and it mounts, but

Code:

mount /dev/sdb2 /mnt/virtual

says no such thing as /dev/sdb2. So I

Code:

ls /dev/s*

and I get /dev/shm but nothing else...

The way this came about is my system was using quick-boot and readahead-fedora, but readahead wasn't working right (Saying no such thing as /var/lib/readahead*.later) so I uninstalled it and quick-boot. Then my computer boots, but isn't recognised as my computer (beaverusiv@chisai) but as beaverusiv@none... tty is permission denied and all sorts of funny stuff.

I noticed 'qinit.multi: No such file or directory' on boot and found out that particular message was coming from a line in inittab about qinit.multi. So I ran

Code:

sudo mount -no remount,rw /
sudo pacman -S initscripts

which reinstalled it, but didn't fix the problem. Thinking I should install quick-init to override my inittab I tried running

Code:

yaourt quick-init

but the Internet was off. Running

Code:

ifconfig -a

found only loopback...

My next plan of attack was to boot from an install disk and run

Code:

mount /dev/sdb2 /mnt
wget http://aur.archlinux.org/packages/quick-init/quick-init.tar.gz
tar xzf quick-init.tar.gz
cd quick-init
makepkg PKGBUILD
pacman -Ur /mnt quick-init 1.11-10.pkg.tar.gz

And then I rebooted into the mess I'm in... I know I've probably done everything wrong, but can I salvage this? I don't want to reinstall, mainly for bandwidth reasons...

Hmmm...

Well, the first thing I would recommend would be; Once you are actually booted to the LiveCD/Install disk, mount the partitions of your hard drive to a mount point on the LiveCD filesystem and chroot into it to do your cleanup. Now, I haven't played in Fedora for a while, but coming from a Gentoo perspective, the following is what I do when I have to fix a drive like yours:

Code:

mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile

At this point, I am within the hard drive's filesystem, with the environment of the drive's OS, but the LiveCD's subsystem running. At this point, I can re-install the packages I need to fix the OS and get it running again. I'm sure there must be a way to get the same thing accomplished in Fedora.

HTH.

Thanks for the reply.

I ran (After finding the right (x64) install disk):

Code:

mkdir /mnt/arch
mount /dev/sdb2 /mnt/arch
mount -t proc none /mnt/arch/proc
mount -o bind /dev /mnt/arch/dev
chroot /mnt/arch /bin/bash
source /etc/profile

And then was able to uninstall and reinstall quick-init which did the trick.
