I had that same problem, and then I did the following. I created a partition with 1MB on the end of each HD that it were gonna be in raid, and kept on partitioning, when I finished my partitioning I removed each partitions of 1MB that I've created in the end of each HD. <div class="gmail_quote">On Mon, Jan 3, 2011 at 9:00 AM, <<a href="mailto:ubuntu-server-request@lists.ubuntu.com">ubuntu-server-request@lists.ubuntu.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Send ubuntu-server mailing list submissions to <a href="mailto:ubuntu-server@lists.ubuntu.com">ubuntu-server@lists.ubuntu.com</a> To subscribe or unsubscribe via the World Wide Web, visit <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-server" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-server</a> or, via email, send a message with subject or body 'help' to <a href="mailto:ubuntu-server-request@lists.ubuntu.com">ubuntu-server-request@lists.ubuntu.com</a> You can reach the person managing the list at <a href="mailto:ubuntu-server-owner@lists.ubuntu.com">ubuntu-server-owner@lists.ubuntu.com</a> When replying, please edit your Subject line so it is more specific than "Re: Contents of ubuntu-server digest..."

It looks like grub has problems to load the /boot related files which are misconfigured to be located on fd0. Please boot into a live environment and check your grub.cfg and post the approriate lines. Something you should also check is: Did you try to create a seperate boot partition on each disk which you may want to mirror? Are there any other disks installed besides your two IDEs? And is the BIOS trying to load the MBR off of these disks which hold a faulty config? Summary: Please give us some more information.

The fix I found was creating a third device for /boot/ partition. 512MB is plenty big for the /boot/ partition. So my structure was like this: /dev/md0 /boot/ /dev/md1 Swap /dev/md2 / On Sun, Jan 2, 2011 at 6:35 PM, Benjamin Griese <<a href="mailto:der.darude@gmail.com">der.darude@gmail.com</a>>wrote: > Hello, > > there seems to be a problem with your grub configuration. > > It looks like grub has problems to load the /boot related files which are > misconfigured to be located on fd0. > Please boot into a live environment and check your grub.cfg and post the > approriate lines. > > Something you should also check is: > > Did you try to create a seperate boot partition on each disk which you may > want to mirror? > Are there any other disks installed besides your two IDEs? > And is the BIOS trying to load the MBR off of these disks which hold a > faulty config? > > Summary: Please give us some more information. > > Bye, benjamin > > > On Mon, Jan 3, 2011 at 01:16, Andres Tarallo <<a href="mailto:atarallo@acm.org">atarallo@acm.org</a>> wrote: > >> H!!!

I don't know, but you should do that anyway as you will most certainly not be able to restore the backup safely if you used such an inconsistent source...
