I don't know how this could be correct or how you could land with such a config. @md: The problem is following: Lennart has a raid 1 on 3 disks, however raid_disks in sdd2 is 2 and dev_roles contains only [0, 1, -1, -1, ...], dev_number is 0 sda2 and sdb2 contain proper raid_disks=3, dev_roles=[0,1,2,-1,-1,..] and dev_number= 0 respectively 1. It looks to me as a seriously damaged metadata but apparently mdadm has no problem @Lennart: did you dd one disk to another or done something like this?
