I have three SATA disks: ad6, ad7, and ad8.
I just installed a fresh copy of FreeBSD 7.0 amd64 (minimal) on ad6s1a.
I setup a gmirror with: gmirror -vb round-robin gm0 /dev/ad6s1a. I
edited my fstab, and told my loader.conf to load geom_mirror.
The machine boots up fine, however I run into an error when I try to
insert an additional component:
# gmirror insert gm0 /dev/ad7s1d
# tail /var/log/messages

I haven't been able to find any explanation for this error. The same
error occurs when I attempt to insert the ad8s1d component.
All of the hard drives diagnose to be working.
