Hi John,

I posted the requested info to the list.

I was wondering if you had a chance to go through it.

Either way do let me know.  I am anxious to get this solved if possible.

Sorry, I was distracted by $realjob...

The only thing that occurs to me is:

# cat /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,0)
#          kernel /boot/vmlinuz-version ro root=/dev/sda1
#          initrd /boot/initrd-[generic-]version.img
#boot=/dev/sda

this. Uncomment it, and change to boot=/dev/md_d0p1, and re-run `grub-install`.

Also, just to be sure, if you haven't installed a new kernel since migrating to RAID, update your initrd - something like `mkinitrd -f /boot/initramfs-2.6.32-220.el6.x86_64.img 2.6.32-220.el6`.

I can't think of anything else.

Cheers,

John.
