$> fuel env create --name region1 --rel 2 --mode ha --network-mode neutron --net-segment-type vlan

*fuel: error: unrecognized arguments: --mode ha --network-mode neutron*

But in the mos8 documentation the above command is provided to configure deployment using "mode and neutron" options. [https://docs.mirantis.com/openstack/fuel/fuel-8.0/pdf/Fuel-8.0-UserGuide.pdf (https://docs.mirantis.com/openstack/f...)]

Could anyone help me in this.
