Description John Fulton 2017-10-16 20:59:32 UTC 
A containerized ceph deployment which didn't pass any overrides but used only the defaults found in: 

-e /usr/share/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-ansible.yaml 

Produced a resources.WorkflowTasks_Step2_Execution Heat resource whose Mistral ansible-playbook call did not pass the osd_scenario parameter to the ansible-playbook --extra-vars run [1]. This resulted in a overcloud deployment with 0 OSDs (0 OSD containers) though the deployment succeeded and evidence of the failure was not seen later until a tempest run. 

Though ceph-ansible should better handle this scenario and fail as per BZ 1502841 [2], the defaults alone should work, provided that the ceph overcloud node has the device /dev/vdb.

Comment 4 Giulio Fidente 2017-10-17 09:42:12 UTC 
Thanks John, as a side note, we might also default storage-environment.yaml to ceph-ansible at this point.
Comment 5 Giulio Fidente 2017-10-17 09:55:42 UTC 
The root cause here is that /home/stack/virt/internal.yaml is overriding the default CephAnsibleDisksConfig passing only 'devices:', see [1]

Instead of closing this BZ though, we might use it to track migration of storage-environment.yaml from puppet-ceph to ceph-ansible if QE agrees with it being a good idea.

Yogev, Sasha, Marius, what do you guys think?
