I cloned a system with 2 drives and 2 raid 1 partitions.
I took a drive out of the old system.
Recreated the raids to get a new uuids.
Partitioned a new drive and added the partitions.
There were a couple other problems that I'm pretty sure was caused by a bad sata controller but think I have that under control.
So here is my problem. Any time I reboot only the partitions on the first drive are active. If I switch drives it's always the first one that is active.
Here is my mdadm.conf
DEVICE /dev/sd*
ARRAY /dev/md0 level=raid1 num-devices=2 UUID=647381d7:fb84da16:f43e8c51:3695f234
ARRAY /dev/md1 level=raid1 num-devices=2 UUID=90b9e6d2:c78b1827:77f469ad:0f8997ed
This is all after reboot:

Any Idea what is wrong?
