Yes, they were created with -V. I seem to have missed that from your
first email that you didn't use -V, sorry about that.
So I have a zfs/bhyve_volumes dataset, which is with "legacy"
mountpoint so it's not mounted anywhere.
and below it I'm creating the zvols with -V.
The purpose of this dataset was to be used as a parent, so I can do
recursive snapshots, etc.
It's interesting that I do have some zvols that are snapshots in
/dev/zvol, however I'm trying to remember if they were created with
older revision, or before I've started fiddling with "volmode"
property.
I will try to update and see is something changes.

Here is the output of the zfs get -r type zfs (but slightly trimmed as
it's several screens otherwise):
