First sorry for the typos, iphone autocorrection got me.

I assue you want to give ctdbd control over samba. 
https://ctdb.samba.org/samba.html

Do you have CTDB_MANAGES_SAMBA="yes" in /etc/default/ctdb?

If so ctdb calls /etc/ctdb/event.d/50.samba. Are you sure you do not 
have exit 1 iin the service_start function any longer?

Seen you enabled the script with

ctdb enablescript samba

I guess you can trigger an start with:

ctdb -n 0 disable
ctdb -n 0 enable

And

ctdb scriptstatus

should show if samba is up and running under ctdb control.

This is differnet because you call smbd and sometimes samba. :-)
