[CentOS] Syncronize systemctl status with reality?

The particular issue is with puppetmaster (which admittedly takes 4 minutes
to actually start, setting TimeoutStartSec=300 in it's unit file stopped
the false timeout report) but I have seen it one other time (don't remember
the details).

systemctl status puppetmaster

However, ps -ef | grep puppet (run just after the above) returns
puppet 1380 1 0 11:26 ? 00:00:08 Passenger RubyApp: /usr/share/puppet/rack/
puppetmasterd
root 2015 1341 0 11:48 pts/0 00:00:00 grep --color=auto puppet

Earlier ps .. also reported
puppet 1355 1166 3 11:26 ? 00:00:01 Passenger AppPreloader:
/usr/share/puppet/rack/puppetmasterd

And, the "bottom line", puppet agent -t on a client works. It reports
finishing the catalog run and the client's yaml files on puppetmaster are
up to date.

Is there a command to tell systemd to re-scan running state and update its
understanding on what it finds? I tried systemctl daemon-reload just to be
sure that didn't solve the problem before posting this.

First glance ity looks like someone has started that puppetmaster manually
at some point. As such it's not in a cgroup systemd is tracking so it isn't
aware of it.

Your attempts to start the service are failing because that manually
started instance already has the port open.

Kill it with pkill -f puppet and then use ss -tnp to check for the port
being freed (wait for any time_wait states to go... which is why I'm not
filtering by listen).

Once it's clear then try starting with systemctl
