Don't use resetconfig. It's for emergencies only. But it doesn't
make any difference here.

Where did this version of Vinum come from? The message that is now
output is
Drive %s has invalid partition type

These are all the results of the first problem.

I don't have any such device nodes. Do you? What's the minor number?

This is "operation not supported by device". I'm surprised you didn't
get error messages from 'vinum create'.

I suspect your real problem is that /dev/da1h and /dev/da2h are set
with file system type 4.2BSD. This is appropriate for making UFS file
systems, and for some obscure reason ccd requires it, but it's a
sure-fire recipe for shooting yourself in the foot. Vinum will
ultimately require a file system type 'vinum', but currently it
insists on 'unused'.
>From vinum(8)
DRIVE LAYOUT CONSIDERATIONS
vinum drives are currently BSD disk partitions. They must be of type
unused in order to avoid overwriting file systems. In later versions of
vinum this requirement will change to type vinum. vinum uses the first
265 sectors on each partition for configuration information, so the maxi-
mum size of a subdisk is 265 sectors smaller than the drive.
You can change it with disklabel -e:
from:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 1173930 0 unused 0 0 # (Cyl. 0 - 358)
h: 1173930 0 4.2BSD 0 0 # (Cyl. 0 - 358)
to:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 1173930 0 unused 0 0 # (Cyl. 0 - 358)
h: 1173930 0 unused 0 0 # (Cyl. 0 - 358)
