I started with installing a FreeBSD 6.3 on my ad0 disk.

Then you've edited the label, but we aren't sure how. You should send the bsdlabel output here for us to look at. > But when I look at /dev/mirror/ it only created 2 partitions, gm0s1a and gm0s1c so the following commands: > > newfs -U /dev/mirror/gm0s1* > mount /dev/mirror/gm0s1* /mnt/* > > Will not work for gm0s1d (var) gm0s1e (tmp) and gm0s1f (usr). Does anybody know what I am doing wrong? Well, I think what you really are wanting, is to mirror your ad0 disk to ad3. In that case, I think you want to make ad0 the first device in the gm0 mirror, and make ad3 the second. Then, you'd need to change your fstab entries, and add geom_mirror_load="YES" to /boot/loader.conf so it would be recognized on boot.
