Re: mdadm spare-group not working for me

Is it possible to influence the order at which the spares are taken
from the group? Reason is that I have four spare partitions on two
ide disks (2 partitions on each disk). Removing a second disk I
noticed it picked the second partition from the same disk. The spares
where added in this order hde7 hda7 hde6 hda6, but mdadm picked hde7
and then hde6. Better would be hde then hda.

No, it is not possible to do that reliably.

mdadm will tend to choose the first one it finds.  So if you add the
best choices as spared first, and then add the poorer choices, it
might be more likely to choose the one you want.
