I end up with a single copy of '/'. However, I partition (both,all) drives identically, so that each has a 200MB-or-so slice at the beginning. I use rsync from a cron job to make backups of '/' to the starting slice of each drive. The reasons I do this are that: 1) Any old FreeBSD boot floppy/CD can read the "mirrors" of '/' in the event that the root drive dies, regardless of the state of vinum. Makes disaster recovery that much easier. 2) You get a little bit of versioning for free. Accidentally overwrite /etc/master.passwd with mergemaster? Just grab the copy from /rootbackup. >> Out of curiosity, what offsets have you had to calculate? > I've read a bit of a chapter from the 4th edition of The Complete FreeBSD: > <http://www.vinumvm.org/cfbsd/vinum.pdf> (or, as text > <http://www.vinumvm.org/cfbsd/vinum.txt>).

Weird. I've never bothered with any of that. I always just call "create" with: sd length 0 drive myDrive1 and let vinum calculate the correct sizes. -- Kirk Strauser
