It's the first I've heard of it.  Do you mean these entries in the
kernel config file?

  # Configuring Vinum into the kernel is not necessary, since the kld
  # module gets started automatically when vinum(8) starts.  This

  # see vinum(4) for more reasons not to use these options.
  pseudo-device	vinum		#Vinum concat/mirror/raid driver

In any case, Vinum was developed with INVARIANTS and
INVARIANT_SUPPORT, so I doubt this is your problem.  If you do have
problems, of course, you should tell me about them.  I note that
you've had problems with Vinum in the past, but this is the first time
you mention INVARIANTS.
