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.
