I tried to compile the 2.6 kernel with raid 1 (software - mirroring) support. After configuration of kernel and creation of the new kernel image, I rebooted the machine and on boot I get the following erors then it stops:
"" Begin: Mounting root file system... ...
Begin: Running /scripts/local-top ...
Done.
/dev/hda: unknown volume type
Begin: Running /scripts/local-premount ...
Done.
mount: Mounting /dev/hda on /root failed: No such device

Done.

I followed the instruction given here, http://www.epimetrics.com/topics/one...e_topic_id=120

Can someone help me ? Did I miss something?

Did you include the file system and raid drivers in the kernel itself? If you configure any drivers needed during boot as modules you need to create an initramfs file.
It is also possible the name of your root has changed. It might now be called /dev/sda instead of /dev/hda..
