Description Andreas Karis 2017-06-16 15:38:13 UTC 
Description of problem:
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html-single/red_hat_ceph_storage_for_the_overcloud/#backwards_compatibility_with_older_versions_of_red_hat_ceph_storage

This is only a copy of the OSP 10 approach.

**Note:** The approach for OSP 10 does **not** work for OSP 11. At the time of this writing, [https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html-single/red_hat_ceph_storage_for_the_overcloud/#backwards_compatibility_with_older_versions_of_red_hat_ceph_storage](https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html-single/red_hat_ceph_storage_for_the_overcloud/#backwards_compatibility_with_older_versions_of_red_hat_ceph_storage) contains the wrong instructions which are only valid for OSP 10.

Additional info:

In Red Hat OpenStack Platform 11, one can enable backwards compatibility by adding the following to one of the environment files, e.g. `storage-environment.yaml`:
~~~
parameter_defaults:
(...)
  RbdDefaultFeatures: 1
(...)
~~~
> If one is using a local copy of `/usr/share/openstack-tripleo-heat-templates/environments/puppet-ceph-external.yaml`, e.g. `cp /usr/share/openstack-tripleo-heat-templates/environments/puppet-ceph-external.yaml /home/stack/templates/`, then one can remove the comment in front of `# RbdDefaultFeatures: 1`
