For 5.3-STABLE you should be using geom_vinum.  That means having
'geom_vinum_load="YES"' in /boot/loader.conf; /dev/gvinum/raid...
in /etc/fstab (in your case); and using gvinum for userland control, not
vinum.  The vinum /etc/rc.conf knobs are not applicable to geom_vinum.

Mixing vinum and gvinum is not recommended.  If you just want a RAID-1
boot setup, you might consider geom_mirror instead.

Cheers,

Paul.
