And you didn't ask, but my mdadm.conf:
DEVICE partitions
ARRAY /dev/.static/dev/md0 level=raid10 num-devices=4

Try adding
auto=part
at the end of you mdadm.conf ARRAY line.
Thanks - will see what happens on my next reboot.
Current mdadm.conf:
DEVICE partitions
ARRAY /dev/.static/dev/md0 level=raid10 num-devices=4
UUID=9d94b17b:f5fac31a:577c252b:0d4c4b2a auto=part
still have the problem where on boot one drive is not part of the
array. Is there a log file I can check to find out WHY a drive is not
being added? It's been a while since the reboot, but I did find some
entries in dmesg - I'm appending both the md lines and the physical disk
related lines. The bottom shows one disk not being added (this time is
was sda) - and the disk that gets skipped on each boot seems to be
random - there's no consistent failure:
[...]
