It will probably take about 500 hours to convert RAIDframe to GEOM and then make it robust. If I was doing it as a day job, that equates to 3 months. Trying to do work on it for an hour or two each evening really isn't possible. I share your concern about the state of software raid in FreeBSD. When I started RAIDFrame I was in a position to devote full-time hours to it. Now, I'm not, and I'm at a loss of what to do about it. Scott
