@aguzman any specific reason you are looking for SMB 3.0? The linux kernel support for SMB 3.x is still maturing [https://wiki.samba.org/index.php/SMB3_kernel_status]
and I ran into issues when mounting FileStorage over SMB 3 on Linux. That is why we released with SMB 2.1 hardcoded. Also are you using our Moby Linux VHDs or your own OS for the hosts?
