Also, keep in mind that vinum does very little in the way of sanity checking. It's very happy to trash your data if you tell it to do something even a little bit unusual.

Raw performance is only one factor in the equation. -Michael Robinson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
