You don't need raidreconf to add a spare disk; just add it with raidhotadd to
the running array.

Thanks for the hint is working!

Another question: did you know a program for monitoring raid array and

Thanks,
Alex

Try mdadm (http://www.cse.unsw.edu.au/~neilb/source/mdadm/). It has a
monitor mode which can be customized to execute any program when an array
(or array member disk) fails. It can also send email alerts.
