Just restored my RHEL 5.3 LINUX system to to different hardware using MONDO. Now while I was successful in doing this on my 32bit system, my 64bit system is giving me the following errors when trying to boot from GRUB:

mount: could not find filestystem '/dev/root'.
Setting up other filesystems
Setting up new root fs
setuproot: moving /dev failed: No such file or directory
no fstab.sys mounting internal defaults
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Switching to new root and running init
unmounting old /dev/
unmounting old /proc
unmounting old /sys
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init

Here is what I have done in an attempt to resolve:

1. reboot system off of red hat rescue cd
2. changed all my devices in the fstab to not point to LABELS but to the actual device I am trying to mount ex:.. /dev/cciss/c0d0p*
3. reconfigured kernel using mkinitrd -v -f initrd*****.img (kernel)
4. changed the mtab, grub.conf and devices file to point to the correct devices and not labels
5. reboot
And continues to give me the same kernel error. ANY HELP is greatly appreciated.

First off, if you copied entire partitions, LABELS should be just fine.

That device paths are very strange to me, never saw it. Cna you post details of your old and new hardware? As much as possible, with the special attention to MB chipset and HDD contrlorers. Also, have you used RAID on any of the systems?

First of all thanks for replying. Here is the current Partition information of the original system:

I would guess that your problem is related to cciss kernel driver. It's for HP Smar-tarray controller that you obviously have on your new sever. maybe you heed to change the type of the driver in initrd image or was it somwhere it /etc/folder? I think I have done something like that when I changed my motherboard from ATI to Nvidia chipset.

You could plug in some other SAS disk and install RHEL and use that kernel and settings for your current server.

DrLove73,

How can I recompile the kernel to have the cciss driver recognized?
