Comment 3 Giulio Fidente 2018-01-04 16:22:37 UTC
This is a late breaking Upgrades DFG requirement for fast-forward upgrades:

[RFE] Fast Forward Upgrade RHOSP10 to RHOSP13

As discussed with members of the Ceph DFG, we would like to explore the possibility of upgrading Ceph directly from the original OSP 10 baremetal  installation of Ceph 2.0 Jewel to the OSP 13 containerised version of Ceph 3.0 Luminous using ceph-ansible in a single step.

At present the containerisation and version update are treated as two separate steps during the OSP 11 to 12 and upcoming 12 to 13 upgrade respectively.

By doing both of these in a single step we would be able to upgrade ceph _after_ upgrading the Controller and Compute roles to OSP 13, allowing for an easier rollback to OSP 10 / Newton if issues arise.

The aim of this RFE is to verify that this is even possible with ceph-ansible today.

Comment 5 Giulio Fidente 2018-01-31 15:48:21 UTC
As per conversation in BZ #1539052 , this is probably going to be implemented entirely in OSP by running sequentially the two playbooks to migrate jewel into containers first and upgrade it to luminous later.
