Vinum is known broken in 5.3. :-) You should be using geom_vinum
instead. It will largely be a drop-in replacement for your above Vinum
configuration. (I am using it on a similar root-on-vinum setup.) The
main changes are these:
1) Load "geom_vinum" in /boot/loader.conf, e.g., add
'geom_vinum_load="YES"' to /boot/loader.conf. This will auto-detect
your Vinum on-disk configuration during boot. You don't need any
rc.conf glue with geom_vinum.
2) Change "vinum" to "gvinum" in /etc/fstab. E.g., use
"/dev/gvinum/root" instead of "/dev/vinum/root"
3) The userland utility is "gvinum" instead of "vinum".
I am using geom_vinum on a root-on-vinum configuration under 6-CURRENT
since before RELENG_5 was branched, and I believe the same holds true
for RELENG_5 and HEAD as far as the above three points are concerned.
I don't know if there are plans to replace vinum entirely with gvinum
(and drop the "g" prefix) for 5.3-RELEASE. Lukas Ertl would know.
Cheers,
Paul.
