Thanks for checking this out.. reviewing the patch, there's no way I
would have figured all that out in that amount of time..

unfortunately, more strangeness -

good bits of disklabel -r /dev/ad1s1:

  a:   78156225          0     vinum    #   38162.219M
  c:   78156225          0    unused    #   38162.219M

- vinum create for the drives as follows:

  drive d1 device /dev/ad1s1a
  drive d2 device /dev/ad3s1a

  fails with the drives being in 'down' state, dmesg reports:

  vinum: Can't write config to /dev/ad1s1a, error 30
  vinum: Can't write config to /dev/ad3s1a, error 30

  (errno.h: #define EROFS 30 /* Read-only file system */)

- newfs /dev/ad1s1a with either vinum or 4.2BSD 'fstype' OK
- mount /dev/ad1s1a with 4.2BSD fstype OK
- ccd as "ccd0 128 none /dev/ad1s1a /dev/ad3s1a"
  labels, formats, mounts OK
- dd if=/dev/zero of=/dev/ad1s1a reports
  dd: /dev/ad1s1a: Read-only file system
- dd if=/dev/zero of=/dev/ad1s1 is fine
  (but blows out the label, as expeced)

when this machine was upgraded to 1.9 a few weeks back,
I made sure to clean out /dev & rebuild, and just did so again
for the ad1 and ad3 devices..

Perhaps I'm misunderstanding the how the new partitions work?

thanks again for investigating
