The ability to specify volume type during server create is complete since 2018-10-16. However, the patches for being able to detach a boot volume and volume-backed server rebuild are in merge conflict/stale. Help is needed here.
It's Chinese New Year / Spring Festival this week so the developers that own these changes are on holiday. Kevin told me last week that once he's back he's going to complete the detach/attach root volume work. The spec was amended [1] and needs another spec core to approve (probably would be good to have Dan do that since was involved in the initial spec review).
As for the volume-backed rebuild change, I asked Jie Li on the review if he needed someone to help push it forward and he said he did. It sounds like Kevin and/or Yikun might be able to help there. Yikun already has the Cinder side API changes all done and there is a patch for the python-cinderclient change, but the Cinder API change is blocked until we have an end-to-end working scenario in Tempest for the volume-backed rebuild flow in nova. I can help with the Tempest change when the time comes since that should be pretty straightforward.
