.Ansible no longer creates unused `systemd` unit files Previously, when installing the Ceph Object Gateway by using the `ceph-ansible` utility, `ceph-ansible` created `systemd` unit files for the Ceph Object Gateway host corresponding to all Object Gateway instances located on other hosts. However, the only unit file that was active was the one that corresponded to the hostname of the Ceph Object Gateway. The others were not active and as such they did not cause problems. With this update of Ceph the other unit files are no longer created.
Description of problem: When we install ceph rgw via ceph-ansible ,the Ansible playbook is inserting entry in systemd for rgw.ceph-rgw-01.service in rgw-02 and rgw-03 nodes .

(In reply to leseb from comment #13) > Doc text is already present. Yes but it was written when the issue was a known issue, and was not updated to reflect that the issue is resolved. I updated it to explain that. Let me know if it needs changes or feel free to make them yourself.
