Hi all,

Seems like I am having the same issue.
I assigned my boot loader to be on /dev/md0 rather then the default of /dev/sda1
Not sure if this is valid for CentOS but on Fedora 15 I had to set the metadata to version 0.90 when creating the /boot array. Without it (so using metadata version 1.0 on /dev/md0 aka /boot) it would not boot.
Patrick, you are spot one. This is a must, and default for CentOS is 1.2 I think.
There is no conversion, you can only backup data from partition on md0 and recreate md0 with:
mdadm --create /dev/md9 --level=1 --raid-disks=2 /dev/sdj1 /dev/sdl1 --metadata=0.90
return data and reinstall grub on sda AND sdb.
While this most likely works, I went a diff route.
Based on this article which is Cliff noted below, I was able to get it working.

The latest dracut fixes the issue but I rebuilt initramfs to be safe.
So my order of operation;
1 - install Centos 6.1 with a software raid 1 config then rebooted of course 2 - yum update 2 - cd /boot 3 - mv initramfs-2.6.32-220.7.1.el6.x86_64.img initramfs-2.6.32-220.7.1.el6.x86_64.img.O 4 - mkinitrd /boot/initramfs-2.6.32-220.7.1.el6.x86_64.img 2.6.32-220.7.1.el6.x86_64 5 - reboot
Hope this helps any futures comrades in arms.
