Setup of a software RAID-1 to an existing system?

[Johan Paul]

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?
