[solved]Arch boot to maintenance readonly mode

nadavvin · 2007-04-13 07:33:55

Someone recommend me to use pata instead of ide since it better and from than I can't boot to arch even they I restore it.

I change the HOOKS in /etc/mkinitcpio.conf to:

HOOKS="base udev autodetect pata filesystems"

and change in the grub to /dev/sda6 instead of /dev/hda6

When I boot I get into maintenance mode with /dev/hda6 I get kernel panic.
I change back to ide and recreate the initrd and now I get kernel panic with both /dev/hda6 and /dev/sda6

What is the problem?

Just changing the hook and fixing to bootmanager isn't enough...
You also have to update /etc/fstab and "s|/dev/hda|/dev/sda|"

Or use Persistant block device names

If you can, please post your current HOOKS-array... And any other changes you made to /etc/mkinitcpio.conf. Maybe something fishy is preventing you from booting...

Also, the next time you try to switch, do this:

# cp /boot/kernel26.img{,.old}

before you generate your new initamfs. That way you can easily revert the changes by editing the grub entry and changing

initrd /kernel26.img

into

initrd /kernel26.img.old

and setting "root=/dev/sda<root> back to /dev/hda<root>, in case you forgot to update your fstab.

The only line which is not comment is:

HOOKS="base udev autodetect pata filesystems"

I try both /dev/hda6 and /dev/sda6 and both I get this message:

Attempting to create root device `/dev/hda6'
ERROR: failed to parse block device name for `/dev/hda6`
       unknown

Ok,
Do you still have an arch-install cd handy?
Boot from that and then do

# mount /dev/hda6 /mnt
# nano -w /mnt/etc/fstab

if the mount-command spits out an error, try changing hda6 into sda6

Now,
in this file, change all your drives partitions from hda to sda, reboot and let me know what happens

I installed Arch from different distro so I don't have Arch install cd.

I can mount from other distro /dev/hda6, some of them it mount at boot, but there non fstab errors.

I can mount manually.

I change in the grub also to hda and sda and in both I get the problem except that I use in sda, The error message contain sda instead of hda.

Bit confused...
In your first post you said that when you boot with "root=/dev/sda6" you get to a maintenance prompt and with "root=/dev/hda6" you get a panic.

You are probably dropped into the prompt somewhere around the filesystem checks, right?

No, I just not copy similar code twice.

when I write root=/dev/hda6 I get the error above which contain /dev/hda
when I write root=/dev/sda6 I get similar to the error above which contain /dev/sda and not /dev/hda

Now it work thanks to z4ziggy help.

The solutionn wast to change to:

HOOKS="base udev autodetect ide scsi sata filesystems"

Arch Linux
