Kinit: cannot open root device

puppet · 2008-10-16 15:43:37

hi,

i'm having trouble with arch linux. when i start it up i get the following message:

kinit: cannot open root device dev(0,0)
kinit: init not found!
kernel panic - not syncing : attempted to kill init!

i don't know what the problem is

this is my grub setting for arch linux :

# (0) Arch Linux
title Arch Linux [/boot/vmlinuz26]
root (hd0,0)
kernel /boot/vmlinuz26 root=dev/sda1 ro
initrd /boot/kernel26.img

and this is my partition:

Apparaat Opstart Begin Einde Blokken ID Systeem
/dev/sda1 * 1 1216 9767488+ 83 Linux
/dev/sda2 1217 3191 15864187+ 83 Linux
/dev/sda3 3192 11976 70565512+ 7 HPFS/NTFS

Have you changed your mkinitcpio.conf recently?

"root=dev/sda1" needs an extra slash like "root=/dev/sda1" instead.

Also, make sure that's really the location of your root partition. "root (hd0,0)" in the previous line refers to the location of /boot. "root=/dev/sda1" refers to the location of the / partition. If you've installed /boot to its own mount point, /dev/sda1 probably is not your root partition.

To make this a little more clear, the grub directive "root (hd0,0)" tells grub where to look for all the files specified in this config file. That is, it tells grub that /boot/vmlinuz26 is on (hd0,0). The root=/dev/sda1 parameter tells linux where all the files IT needs are (for instance, /bin/init).

Ah thanks for the explanation. That lifts a layer of abstraction for me about what each part does.

puppet · 2008-10-22 17:23:30

it's all on the same partition. so the grub is looking in the good partition.

edit: it works now. the '/' i forgot.

thx for the help
