vinum does not like FBSD 5.4
or vice versa
it is not supported

you could manually 'setstate up var.p1.s0' and 'setstate up var.p1'
that should work
i tested it with a raid 1 mirror, removed the HD that came up ok and  
checked if the mirror would still come up, which it did
i do definitely not recommend it though
while you aren't still useing the raid, go use something else than vinum

you'll be getting this all the time if yu continue to use vinum in  
FBSD 5.4

do 'vinum read' but expect to have kernel panics...

again, i'd stay away from vinum/gvinum in FBSD 5.x  if i were you...
if you don't, come join me in the mental institute for stubbern vinum  
users :)
