Hi, that gmirror together with glabel cannot be used looks like a problem introduced with 8.0-RC1 to me. What I did: 2. Installation 3. reboot 4. mirror Root-hdd sysctl kern.geom.debugflags=17 gmirror label -vb round-robin gm0 da0 gmirror load echo 'geom_mirror_load="YES"' >> /boot/loader.conf echo 'geom_label_load="YES"' >> /boot/loader.conf 5. adjust fstab vi /etc/fstab :%s/ad/mirror\/gm/g 6. reboot 7. mirror Root-hdd gmirror insert gm0 da1 gmirror status 8. wait until gmirror is done 9. reboot 10. glabel status With 8.0-RC1 I see only da0s1a, da0s1d, da0s1e and da0s1f as Components shown by glabel(8). With 8.0-BETA3 I see mirror/gm0s1a, mirror/gm0s1d, mirror/gm0s1e and mirror/gm0s1f as Components which would be correct here. I use old IBM 2GB DFHS harddisks for that tests. I have a bunch of them so I used for both tries "fresh" drives. I can't see what has changed here between BETA3 and RC1 but something must have changed in a way which renders gmirror together with glabel on RC1 non-working. I just did that as testing the configuration I want to use for my fileserver when the new harddisks arrived but now I'm not sure If I should rely on gmirror+glabel....
