The export_ceph method in python-tripleoclient fails when using ceph-ansible with a 17.1 inventory file: File "/usr/lib/python3.6/site-packages/tripleoclient/export.py", line 196, in export_ceph mon_ips = export_storage_ips(stack, config_download_dir) File "/usr/lib/python3.6/site-packages/tripleoclient/export.py", line 178, in export_storage_ips for hostname in inventory_data[mon_role]['hosts']: KeyError: 'hosts' This is causing OSPdO deployments during FFU to report failure at the very end of the deployment (it will automatically export and store the ceph data). Once the cephadm adoption step are complete the issue is resolved.
