trying to expand a zvol-backed bhyve guest which is UFS

[tech-lists]

Hi,

context is 12-stable, zfs, bhyve

I have a zvol-backed bhyve guest. Its zvol size was initially 512GB
It needed to be expanded to 4TB. That worked fine.

The problem is the freebsd guest is UFS and I can't seem to make it see
the new size. But zfs list -o size on the host shows that as far as zfs is
concerned, it's 4TB

On the guest, I've tried running growfs / but it says requested size is
the same as the size it already is (508GB)

gpart show on the guest has the following

# gpart show
=>        63  4294967232  vtbd0  MBR  (4.0T)
          63           1         - free -  (512B)
          64  4294967216      1  freebsd  [active]  (2.0T)
         4294967280          15         - free -  (7.5K)

=>         0  4294967216  vtbd0s1  BSD  (2.0T)
           0  1065353216        1  freebsd-ufs (508G)
  1065353216     8388544        2  freebsd-swap  (4.0G)
  1073741760  3221225456               - free -  (1.5T)

I'm not understanding the double output, or why growfs hasn't worked on
the guest ufs. Can anyone help please?

thanks,
