Why not use torrent as a workaround?

I just downloaded the freebsd-openzfs-amd64-2020081100-memstick.img
image and installed it as a fresh install. (ZFS install)
Then i imported a pool that is a mirrored zfs pool of 6 WD drives
created with FreeBSD 12.1 without any problem.

The only thing i see when the ZFS module is loaded is the message can't
handle raw ops yet!!!

# kldload zfs
can't handle raw ops yet!!!
can't handle raw ops yet!!!
can't handle raw ops yet!!!
ZFS filesystem version: 5
ZFS storage pool version: features support 5000
can't handle raw ops yet!!!

regards
Johan

I'm working on it - Ryan reminded me of it today. It will probably get
fixed before the merge. KSTAT_TYPE_RAW isn't supported in legacy ZFS,
so strictly speaking it's not a regression (apart from the annoying
reminder on debug kernels).
