Actually, it doesn't matter if you make your md device out of whole
disks or not, it's the attempt to find a partition table on the md
device itself that is generating this message. This is a side effect of
the recent kernel change to allow any block device to be partitioned and
merely indicates that no partition table was found on your md device.
It's normal. In fact, it might be worth suggesting that the message go
away. If there's no partition table people generally know that because
there are no partitioned dev files ;-)
