Thanks for the reply. I stumbled on the answer by luck soon after my post. In my case, the md0 raid1 /boot device was newer and had been set to partition type fd "Linux raid auto detect".... [by welbo]

I setup a RAID5 (md1) and a RAID1 (md2) using the Ubuntu install image. During setup I said to put /boot on the smaller RAID1. I put "/ "on the RAID5. My boss told to put the \boot and other low activity folders on the RAID1 and put /usr and /var on the RAID5. Did I do this or do I have duplicate boot directories on each RAID?
I currently have openSuse 11.0 installed on a software dmraid raid5 volume. Today I tried to install openSuse 11.2 instead, but I got stuck in the partitioning. I have a /home partition which is also a software dmraid raid5 volume and I want this partition to be left untouched.
I have an operational Ubuntu Server 12.04 with only one HD (1Tb).
I need more capacity and stability, so I bought last week 3 HD(1Tb each) to make a RAID5 and migrate the information of the old HD to the new RAID system.
I created the RAID5 on the three HD using mdadm tool and apparently works fine.
When in YaST/System/Partitioner I try to create RAID for my second HDD which is named "sdb".
My original "sda" hdd is partitioned as follows:
dev/sda, disk type
dev/sda1, linux swap, swap, swap
dev/sda2, linux native, ext3, /
dev/sda3, linux native, ext3, /home
I lost the ext3 File system after resizing the Partition on an md raid device. The whole story:
I added an SSD and freshly installed Centos 6. The Raid devices for the former / and swap had to be deleted and the Data Partition should receive the entier disc capacity. I started with two hard disks, having three partitions type fd and three raid1 devices.
