Under the Live CD, I see ada10 and ada0 are the same 150GB data, and also see ad11 and ada1 are the same 1TB data. /dev/ad10p2 / /dev/ad10p4 /usr /dev/ad10p5 /var /dev/ad10p6 /home and ada0 show the same data, then.... /dev/ad11s1 /data with ada1s1 shows the same data I assumed these were the two pairs of disks with the same data handled by gmirror. -- Robert
