No start/stop messages in CentOS 7 service management

I'm not sure when this changed, but it appears that our CentOS 7 start/stop scripts are no longer printing out any status of whether the start/stop succeeded:

[root@ip-10-0-16-101 ~]# service couchbase-server restart
Redirecting to /bin/systemctl restart couchbase-server.service
[root@ip-10-0-16-101 ~]# /bin/systemctl restart couchbase-server.service
[root@ip-10-0-16-101 ~]# service couchbase-server stop
Redirecting to /bin/systemctl stop couchbase-server.service
[root@ip-10-0-16-101 ~]# service couchbase-server start
Redirecting to /bin/systemctl start couchbase-server.service
[root@ip-10-0-16-101 ~]#

It also appears that the "start" command is returning immediately and so doesn't have a chance to fail.
