I crawled the archive of the list and found that --invalid-backup with a
faked and empty backup might help. Here is the result:

So no luck at all. All disks are accessable using smart which makes me

Hello every one,
I have a huge problem. I started to grow a array with ( the added
device is /dev/sde )
# mdadm --grow --raid-devices=13 /dev/md0 --backup-file=md0.bak
after that there way 0 disk activity so i checked it with
# cat /proc/mdstat
everything looked fine but speed was 0K/sec for about 1-2 hours. I
decided to reboot the system as grow should continue after that. After
that the array wasn't assembled at all. So i wanted to do it myself:
# mdadm --assemble /dev/md0 /dev/sd[b-n] --backup-file=md0.bak
--verbose
