Re: Unable to find root device - after updating

This is my first day with Arch Linux, though not with Linux and I ran into this issue after installation.

I followed the instructions on this thread, though that has not solved my problem.

I first installed using the installation CD and later on did a re-install from CD by selecting remote repositories with the hope that the issue gets resolved. It still is not resolved.

Would appreciate any help.

Re: Unable to find root device - after updating

Upgraded to kernel 3.3.8 last night, try to boot today, this exact problem. It threw me into the initramfs recovery shell.

`shutdown`? no. `halt`? no. `reboot`? nope. `logout`? no. `exit`? nope. Ctrl+D ... panic: attempting to kill init. (In retrospect, maybe I could have `init 0`'d it?)

I did a hard reboot, and the system actually booted on the next try. Everything seems fine, but I'm kind of scared to reboot now. Hoping to figure out the source of the problem. After reading this thread, it looks like just running mkinitcpio again only sometimes works.

Re: Unable to find root device - after updating

Try to reinstall linux after the chroot. So do what pineapple-biku said, but also reinstall linux:

pacman -Syyu udev mkinitcpio linux
mkinitcpio -p linux
reboot

edit: The module not found errors and the fact that for some it works if they install linux-lts suggest something is wrong with the kernel.

Re: Unable to find root device - after updating

Hi all!

I'm still eager to know what is causing this. I'm having a VPS with Arch on and there I can't mount any ISO image just reinstall the with an old Arch build on. So I'm waiting to upgrade Kernel until someone has fixed this.

Re: Unable to find root device - after updating

Caused by.... not reading the news? Not taking care of safe initramfs creation before rebooting? There's no bug here. At least, none that's been reported to me.

Re: Unable to find root device - after updating

Well I red the news and upgraded my system as announced. But the initramfs creation didn't went so well even though I ran mkinitcpio -p linux once more after all upgrading. Got my laptop running via mounting from CD. But for me it looks like there might be a bug.

Re: Unable to find root device - after updating

I too noticed the news and did the updates accordingly. Things went well at that time. My system broke on a more recent update. (Besides, I don't use udev in my mkinitcpio config)

I encountered this problem after updating; linux (3.3.7-1 -> 3.3.8-1), mkinitcpio-busybox (1.19.4-2 -> 1.20.1-1), and mkinitcpio (0.9.0-2 -> 0.9.2-1) among others.

My mkinitcpio config is customized for my system to be extremely lean and fast:

MODULES="sata-nv sd-mod ext4"
BINARIES=""
FILES=""
HOOKS="base"
COMPRESSION="cat"

When the system didn't work, I booted the install CD to rebuild the image, and I also built the default config with udev autodetection just in case. The rebuilt custom image still didn't boot, but the autodetect image did. I compared the output of lsinitcpio for the two images to see if maybe I'm missing a module for the new kernel, but besides sr-mod and pata-amd (which I don't need since my configuration is for sata), nearly everything seemed to be usb or sound related.

I will try to investigate further, but does the forum have any tips for me?

Re: Unable to find root device - after updating

Alright, I have (temporarily) fixed my issue by adding the udev hook, but this should not be necessary for my setup.

lsinitcpio reveals that there are no extra modules added to the image with the udev hook, but /dev/sda1 cannot be found without it.

Unfortunately, my usb keyboard doesn't work at the prompt following the error message (adding the usbinput hook does not fix this), so I cannot investigave /dev to see what devices do exist, and I don't have a PS/2 keyboard handy at the moment.

If memory serves, there used to be a message at bootup saying something like "/dev/sda1 not found, creating node", and the script presumably ran an mknod command. Perhaps this functionality has been removed in mkinitcpio 0.9.2?

After having gone through the entire thread and did few thing menltioned in the thread..still I am landed in "recovery shell"...what the heck!

Now what I did?

Chroot'ing to Arch

get usb in

then

build linux-kernel

then

put the usb into the hook

Still failing!!!

Kindly suggest what more has to be done to get it work!!

I am not a doctor, but those I know are pretty clear.  If a patient has a symptom, the first diagnoses should rule out the common causes, before moving to the exotic ones.

This thread is about the exotic.  Did you verify that your grub configuration correctly identifies the boot disk?  If you are using UUIDs, is it possible the UUID for the root partition has now changed?

If you are not using UUIDs, did the BIOS somehow reorder your disks?

I am impressed by your query!

Now let me tell you..what I find out I have separate boot physicall partition..I run Slackware,Gentoo,Arch,Debian,Scientific Linux and Fedora....all physicall partition..and I boot through Fedora grub..

And I have had cross check the grub entry and find out the UUID by chrooting to Arch and typing bklid binary ...Then put it back to the grub enlisting.

Okay let me five you my UUID list entry :

Re: Unable to find root device - after updating

1) The thread suggest to reinstall udev, linux and mkinitcpio (probably that's not the problem)
2) After reinstalling these things, you should run 'mkinitcpio -p linux'. That will be the problem, definitely because you added a hook. After editing mkinitcpio.conf, you should always run 'mkinitcpio -p linux' again.

Re: Unable to find root device - after updating

pineapple-biku thank you!

I upgraded linux and after reboot the system failed to boot.

I hope it won't break like this at every kernel upgrade.
Is this common or just bad luck? What's the cause?

OK, found that Yaourt was the problem (depmod not found), see https://bugs.archlinux.org/task/27334

Which aur wrapper is better? packer will do it?

And that's why I don't trust Yaourt and never use it, also that's why I do -Syu with pacman - pacman is official Arch Linux package manager. Packer is working for me very well but still I use it just to manage AUR packages. As their names indicates, these are helpers not pacman replacements wink
