From the log:
2017/01/12 11:30:26.409529 ctdbd: Starting event daemon /opt/samba/libexec/ctdb/ctdb_eventd -e /opt/samba/etc/ctdb//events.d -s /opt/samba/var/run/ctdb/eventd.sock -P 7252 -l file:/var/log/log.ctdb -d DEBUG

2017/01/12 11:30:26.425455 ctdb-eventd: socket bind failed - /opt/samba/var/run/ctdb/eventd.sock
After removing /opt/samba/var/run/ctdb/eventd.sock it starts.
I guess you may want to add code to remove stale sockets like it's already done in ctdbd:
2017/01/12 11:30:26.409335 ctdbd: Removed stale socket /opt/samba/var/run/ctdb/ctdbd.socket
eventd is supposed to remove the socket file when shutting down.
How did you manage to get into this situation?
By shutting down. :) With systemctl stop ctdb.
