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?

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. =2D-=20 Kirk Strauser --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQA/Ht3k5sRg+Y0CpvERAp+6AJ4oJt9CK/7TqAh3FLgtnZlLW/GvmQCfRHCI pF3ByQZXltXcUb1vhGfVltk= =RTnr -----END PGP SIGNATURE----- --=-=-=--
