I added the DEVICE /dev/sd[bcde]1 to mdadm.conf and that apepars to have
fixed the problem. 2 reboots and it worked both times.
An alternate fix in this case would be
mdadm --zero-superblock /dev/sdb
to remove the old superblock that is confusing things.

That fails as:
[root@homepc ~]# mdadm --zero-superblock /dev/sdb
mdadm: Couldn't open /dev/sdb for write - not zeroing
[root@homepc ~]#
I also discovered that /dev/sdc appears to have a superblock which maybe
explains why # mdadm --examine --scan throws up three arrays. Trying to
zero the superblock on /dev/sdc gives the same error.
