Glad to hear you got it working.
'default' references "vfs.zfs.vol.mode":
sysctl -d vfs.zfs.vol.mode
vfs.zfs.vol.mode: Expose as GEOM providers (1), device files (2) or neither
It's probably modified unintentionally on your host. On the other hand I
remember someone documented that under unclear circumstances, it needs
to be set explicitly to 'geom' even with the sysctl beeing still the
default "1" (=geom).
