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. Is this a fair assessment? Are there any factors I've missed? Which solution is likely to suit the situation better? Jonathan
