The socket is there and is renewed upon each ctdb (re) start. smb.conf
refers to the same socket.

Hi
The changes we made were necessary for ubuntu. In ubuntu smbd is called
smbd, not either samba or smb.

The script is from the standard Ubuntu ctdb and samba install using
synaptic. Because samba on ubuntu is not built with cluster support, we
built 4.1.11 from source. The script at /etc/init.d/smbd works fine
manually using:
sudo service smbd start
etc. etc.

Cheers,
Steve
