Description of problem:
Ceph-Ansilbe playbook details [rgw] section as supported in ceph_conf_overrides but this section is not supported in Luminious:
###################
# CONFIG OVERRIDE #
###################
# Ceph configuration file override.
# This allows you to specify more configuration options
# using an INI style format.
# The following sections are supported: [global], [mon], [osd], [mds], [rgw]
#
# Example:
# ceph_conf_overrides:
# global:
# foo: 1234
# bar: 5678
#
#ceph_conf_overrides: {}
We should actually be specifying the following for RGW's:
If the daemon you specify is a Ceph Gateway client, specify the daemon and the instance, delimited by a period (.). For example:
[client.radosgw.instance-name]
# settings affect client.radosgw.instance-name only.
Version-Release number of selected component (if applicable):
RHCS 3.3
