Tobi,

Your mdadm is a little old. Could you please try rebuild it from
latest source code?

Thanks,
Song

What is in your mdadm.conf? Usually found in either /etc/ or in
/etc/mdadm/

Created with /usr/share/mdadm/mkconf:

HOMEHOST <system>
MAILADDR root
ARRAY /dev/md/test  metadata=1.2 UUID=d59de5cc:02f560ed:ebcb9400:491955d7
name=debian:test
    spares=1

The "spares=1" is for the journal device. The "mdadm --examine --scan"
command produced that for me as well but since it seemed odd I deleted that
part. Since there isn't actually a spare it seems incorrect. I've never
tried to boot with "spares=1" so I don't know if removing it will make any
difference.
