There's nothing in the documentation that says you have to "read" all subdisks of a striped plex in one command, or else you will trash the plex. And banisters are extremely important in 24x7 production environments. In my experience, downtime caused by operator intervention is more common than downtime caused by mechanical failure. So, while a flawless vinum installation may well be possible, it is still far too fragile at this point for me to bet the business on it. -Michael Robinson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
