How to force Samba to use SMB 3.0?

With SMB 1.0/CIFS being removed from Windows 10 in Redstone 3 update due to vulnerability, this will conk out a lot of systems relying on older network hard drive enclosures.
I have a Linux-based device (Raspberry Pi) that I could connect up to the drive with USB, but I'm not sure on this point:
Is there a way to restrict Samba on the Pi to using only SMB 3.0?
security configuration samba smb

Use server min protocol option in smb.conf:
This setting controls the minimum protocol version that the server will allow the client to use.
Possible values are listed in documentation for server max protocol option.
The documentation matching the samba version installed on your system should be available with man smb.conf.

Yep, I've added it to[global], but it's not accepting server min protocol at all, min protocol of SMB3 or SMB3_00 are both not accepted either. [2017/10/16 14:03:57, 0] smbd/server.c:1053(main) smbd version 3.6.6 started.

You should refer to the documentation matching the version of samba you have. The old version (3.6.6) of samba on your system likely doesn't have support for SMB3, check the documentation on your system. (Ubuntu 12.04 LTS ships with 3.6.3, which is quite close if you need online documentation:man smb.conf)

I've doneapt-get update/upgrade. According to Samba wiki, the recommended Linux kernel SMB3 support is kernel version 3.18 or later (or equivalent, ie cifs module version 2.04 or later). I've checked cifs via modinfo cifs, I have 2.06. I've checked kernel version viauname -a, I have 4.1.19, andcat /etc/debian_versionis 7.11. The Pi should support a better samba, any ideas why not?

cifs module is for kernel client, not server which is userspace. For SMB3 you need Samba 4.0.0 or later.
