But setting this to 6 and --scan this works. Thanks for the quick help! 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.
