how to convert a non-RAID system to RAID1?

[Matthias F. Brandstetter]

Hi all,

I have a FreeBSD 4.10 server running on one IDE disk. Now I installed a 2nd 
disk which I want to use for RAID1 together with first disk.

My question is: How can I convert this setup to a software RAID1, without 
rebooting the machine or something like that. Is this even possible?

I know this isn't much work under Linux, but since I just started with 
FreeBSD, I wanted to ask you guys before I play with this production 
machine... ;)

Hope you can help me and point me to the right directions!
I've allready read vinum handbook on freebsd.org, but I am not sure how to 
convert an existing non-RAID system to RAID1.

Greetings and TIA, Matthias
