Forget 'systemctl reload'
Forget 'killall'

This is the one that should work, this should make smbd reload smb.conf
You could try 'smbcontrol all reload-config'
You should also note, that this will probably need to be run by root or
with sudo.

If it still doesn't work, try raising the log level and see if anything
pops out.

well, at least -HUP produces some logging and when smbd says "Reloading
services after SIGHUP" it should do so or it's a bug

Process: 1072506 ExecReload=/usr/bin/kill -HUP $MAINPID (code=exited,
status=0/SUCCESS)

He doesn't want to actually stop smbd, he just wants the config reload,
without stopping anything.

Hai, 

As Harald showed, this is a known thing, this did hit samba, after the multi
threaded support.
See also : systemctl cat smbd.service 
For what works what not. 

For a reload the kill -HUP MAINPID is, as i know, the only thing that works atm.

Is this a AD DC  or a member? ( sorry didnt follow the complet thread ) this
catch my eye just now.
Imo, for a member it should work, but i've not tried it. 


Greetz, 

Louis
