When you're starting the dlm through pacemaker, be sure that systemd is
not also starting it.  I don't think pacemaker is happy if dlm_controld
is already started.

In /etc/dlm/dlm.conf put

log_debug=1
debug_logfile=1

then you should see all the debug info in
/var/log/dlm_controld/dlm_controld.log
