When using newer Elasticsearch versions you will receive the following error
when trying to start: elasticsearch | max virtual memory areas
vm.max_map_count [65530] likely too low, increase to at least [262144]

This could be solved by increasing the vm.max_map_count value via sysctl.

Fluentd config actually used two keywords to named log level:
"log_level" and "severity_label".
This doesn't allow to search and sort ALL logs in Kibana using a unique
field (ex: log_level).
This fix standardize log level keyword naming.

Libvirt 3.2.0 (latest version in centos) seems to
have changed behavior of dynamic_ownership.

ARA does not work yet with ansible 2.4, this change
pins to lower version to make gates work.
Revert once ara works with 2.4

When an external Ceph cluster is used, the "filesystem_store_datadir"
option is set in the "glance-api.conf" configuration file.

It should not, it's because of this condition:

  {% elif enable_ceph | bool and glance_backend_ceph | bool %}

When external Ceph cluster is used "enable_ceph" is false and
"glance_backend_ceph" is true.

glance_backend_ceph variable should be enought for this condition.
