'man ccdconfig' contains some good examples. I'd use an interleave of 1152. First disklabel each disk, then use ccdconfig to stripe the partition you've configured on each disk all together. You might want to use postfix rather then qmail, but it's up to you. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
