OpenMediaVault – to disable SMBv1 and enable higher protocol

root@OpenMediaVault:/etc/samba# smbd –version
Version 4.9.5-Debian

it should be sufficient to put this two lines in smb.conf

root@OpenMediaVault:/etc/samba#  vi /etc/samba/smb.conf
[global]
server min protocol = SMB2
server max protocol = SMB3
