I created a degrated raid5 on top of md1 and hde1. Then moved the data =66rom /dev/hdk to the mounted raid5, and then added hdk1 (repartitoned) to the array. The sync began, but after that hde1 was faulty. I removed it, readded it, but now I've a raid5 with only one active disk (which should not be possible imho, a raid5 always needs 2 disks) AND what's even stranger for me, I've two spare disks. Is there a way to force rebuilding the array? I am a bit confused, because I thought Linux would rebuilt the array automaticly, when having spare disks. The output of mdadm and some debug can be found at http://home.schottelius.org/~nico/linux/debug/raid/raid5.strange I am happy for any hint, because I did not find documentation, which refers to having two spare disks with raid5. And as much as I know from the Software-Raid howto, Linux should rebuilt it automaticly, shouldn't it? I am happy for any hint, I am currently not rebooting the system or umounting the path, because I do not know whether the array will come up again.
