I use gmirror for this very purpose.  It works well.

Subject: Mirroring: gvinum or gmirror?


> I'm setting up a remote server with two identical hard drives, running
> FreeBSD-6.1. I want to set the drives up as a mirror for data redundancy.
I
> also want to be able to break the mirror when I need to update the OS or
> installed software, so that if anything goes wrong with the update on one
> drive I can boot back to the other one, or if all is well, re-establish
the
> mirror and synchronise to the updated system. I have serial console access
> including BIOS console redirection.

> Based on web and Usenet/mailing list searches, gmirror looks more
> straightforward for this simple case, gvinum more flexible but poorly
> documented, and the most recent comments I can find (still all 6+ months
ago)
> seem to suggest that gvinum hasn't completely stabilised for production
yet.

solution
