Question adding main device into raid-array not working

This command is successful:
mdadm --create /dev/md0 --level=1 --raid-disks=2 missing /dev/sdb1

However when I am trying to add the main device with this command:
mdadm --add /dev/md0 /dev/sda1
I get an error message that the device is busy.

Should I execute the whole tutorial from a live cd ?? But then all the configurations would happen on the system of the live cd not the installed one...

Any tip would be greatly appreciated!
