Manjoro LinuxでSambaを起動すると、デーモンは起動できませんでした。 Sambaは誤って設定された「サーバーの役割」を検出して終了しました。

私は最近manjoro linuxでsambaを起動しようとしました。

systemctl start samba.service
systemctl status samba.service

At this time the 'samba' binary should only be used for either:
'server role = active directory domain controller' or to access the ntvfs file server with 'server services = +smb' or the rpc proxy with 'dcerpc endpoint servers = remote'
You should start smbd/nmbd/winbindd instead for domain member and standalone file server tasks

STATUS=daemon failed to start: Samba detected misconfigured 'server role' and exited. Check logs for details, error code 22

私がここで何を見逃しているのかよくわかりません。
