I tried this and I got panics consistent with severe data corruption when running with the integrated mirroring enabled. It was acting like writes were going to only one side of the mirror but it was reading from both. I pawed through the linux driver and decided that it requires OS support, since the linux driver knows how to access the underlying physical devices. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
