Why mirror the whole disk? - i've heard vinum is used here (I have yet to play with it) - ccd's (see ccdconfig) are working fine for me currently ( I have similar hardware with 1x1.5G IDE and 3x512M SCSI-2's on an Adaptec 2940 card - the SCSI's are setup with 3 swap partitions and some ccd's holding /var and /usr ) Hope this helps Regards Richard To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
