Johan, The canonical answer is to repost to freebsd-questions, which enjoys a larger readership. But I'll try -- your question is interesting b/c I'm in the same boat, except w/ CURRENT. As you said, breezing through the handbook will show a lot of detail, but perhaps it does not directly address mirroring a live fs.
Aside from the handwaving, you might check http://www.vinumvm.org/. There seems to be a relevant (if a little dated) article: http://www.freebsd.org/doc/en_US.ISO8859-1/articles/vinum/index.html It may be possible to mirror partitions, even if half of it is live. Were this not the case, it's prob possible to boot the install cdrom and play some tricks with dd or dump to sync the disks. Perhaps they could then be mounted, vinum set up, and then booted into. It would be fantastic if the freebsd installer had the ability to run raid 1 right out the chute. Doubtless, there's a number of us w/ legacy servers having two disks but no hardware raid. Good luck. Share your notes (at least to newbies) once you get it working!

Hi all! I am pretty new to FreeBSD but thought it might be a nice idea to migrate from a Linux server to a FreeBSD one. My question is regarding software RAID-1 for this FreeBSD box. I have two IDE equally sized hard drives and I installed FreeBSD 4.8 on the other one. Now the question is: can I make a RAID-1 array of these two disks while FreeBSD is installed on the other one (using vinum or other...)? Or how do I get RAID-1 to work on these two disks? I've read some of the vinum documentation but it is unclear to me if it is possible to set up a RAID-1 on a running disk system - and if my assumptions are correct, that it is impossible, it is unclear to me how to set up this RAID-1?
