[ClusterLabs] can't create master/slave resource

We have a 3-node cluster (CentOS 7.4) with several systemd resources
configured. One of them I would like to create as a master/slave resource,
so following the RedHat documentation:

pcs resource create ivr systemd:japp at ivr - works, the service is started on
one of the nodes.
pcs resource master ivr-master ivr - doesn't work as expected: the service
is stopped and the output of pcs resource show doesn't list it anymore.
However, if I try the command again, I get an error saying the resource ivr
already exists! I have to delete the resource and recreate it to get the
service to run.


Am I doing something wrong?
