Hi Ravi,
thanks for your reply. I tried killing the glusterfsd process and I 
confirm that the client does not see any pause, indeed.

I was thinking that during the shutdown procedure systemd would kill the 
processes by itself; which it *does*, but only if the glusterfsd.service 
is enabled/started.

By default, the systemd service installed on CentOS 7 + Gluster 6.0 SIG 
does not start glusterfsd.service and so, in the shutdown phase, it does 
not stop it.

Thanks very much for your information.
