Re: Problems booting after new motherboard - label /1 not found

Hi Again,

Just to let you know I have fixed this issue, it was because of a missing driver for the disk. What I did to fix it was this :-

1. Boot from the rescue CD

2. chroot /mnt/sysimage

3. edit /etc/modprobe.conf and change the scsi_nv to scsi_via

4. Delete (or rename for safety) /boot/initrd-2.6.11-1.1369_FC4.img

5. /sbin/mkinitrd /boot/initrd-2.6.11-1.1369_FC4.img 2.6.11-1.1369_FC4

Then a reboot and all works as expected. Hope this solution helps somebody.

Regards

Ben

Hello All,

I have been using FC4 as a MythTV box for 18 months or so now and all has been well. I'm not really all that upto speed with the Linux way of doing things, so am a little stumped with this problem.

I went on Holiday and when I came back the power supply had blown in the unit, and after replacing the power supply it looked like it had taken the mother board out with it (or maybe the motherboard took the power supply out, who knows). Anyway I had to put a different motherboard in as I could not get the same one as I had before. I now have an MSI K8MM3 board in, before I had a NFORCE3-A.

When I try to boot I get the following :

Booting 'Fedora Core (2.6.11-1.1369_FC4)'
kernel direct mapping tables upto ffff810100000000 @ 8000-c00
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83

initrd /initrd-2.6.11-1.1369_FC4.img
[Linux-inetrd @ 0x37ea9000, 0x146041 bytes]

.
Decompressing Liux...done.
Booting the kernel.
Rd Had nash version 4.2.15 starting
mkrootdev: label /1 not found

switchroot: mount failed: 22
Kernel panic - not syncing: Attempted to kill init!

And there it hangs. I am guessing its something to do with the new MB having different disk controllers in it.

I have tried booting with the FC4 recover cd, and it boots. I notice it says, "Loading SATA_VIA driver", so I wonder if I need to get that driver onto my existing system? or would that already be there?

It says the following files systems were not unmounted cleanly /dev/ sda1 I continue anyway, it then says an error occurred trying to mount some of my filesystems.

It has mounted /dev/sda1 on /mnt/sysimage/boot as RW (ext2) and that seems to be fine and intact, its also mounted /dev/sda2 on / mnt/sysimage/ as RW (this on is ext3). Again it all seems to be intact.

The other volume I have is the data volume and is JFS on LVM, this I guess is where the error occurred during mount so is probably not really an issue at the moment, as the boot and root partitions are fine.

How should I proceed so that I can get the machine to boot again? I hope I have given enough detailed information in this request to be useful.

Regards

Ben
