On my newly built machine, in which all filesystems are on RAID array,
one of the arrays does not show up with the command:
mdadm --examine --scan
Why is this? And is there anything I can do to fix it?

I suspect that I may have found an answer to this question -- the
array that does not show up is formed from partitions that are logical
partitions instead of primary partitions. I'll try deleting the
partitions and re-creating as primary.

That's not it, I just checked and mine show up just fine, even with an
old kernel and mdadm.

I have destroyed and re-created the arrays and the problem has gone away.
