@humblec @Madhu-1 Will this release also include the following issues and will Ceph CSI RBD snapshots enter beta in this release?

• Add support for smart cloning in rbd #675 (tagged with the 2.1.0 release label)
• Add support for standalone snapshot creation and cloning support #693 (linked from Add support for smart cloning in rbd #675 but not labeled)

[humblec]

@ntolia planning to get these in next feature based release. Unless there is a concern from community about having features in minor release ( y release), this should be part of 2.1.0.

[ntolia]

Thanks @humblec. If we truly are following SemVer and not doing breaking changes (snapshots is alpha anyway and can be broken though), I think we should be good, right? Looking forward to 2.1.0!

Snapshots is beta in k8s v1.17 and cloning is beta in v1.16.

Snapshots is beta in k8s v1.17 and cloning is beta in v1.16.

@dillaman What I have found is that there is K8s snapshots support and then Ceph CSI snapshot support. The latter is still in alpha from what I can make out.

Yeah, that is ( snapshot is still in alpha) our escape path :) , however couple of things around it like , having some responsibility for the code we have here, bringing or wiping all the instance of previous spec of snapshots from the code..etc need some thought. figuring out the same meanwhile,

[Release call update]
There is a GA date change or slip of 2 weeks to accommodate couple of important features or bug fixes. We are also planning to release v2.0.1 in between.

[humblec]

[Release call update]
The final decision here is to release v2.1.0 as planned with bug fixes/enhancements ..etc and defer couple of features ( snap/clone) from this release to v3.0.0 as we are currently revalidating the design/implementation of those features in depth to support some more use cases which have to be supported in near future.

@Madhu-1 please add details if I missed any.

@Mandu-1 @humblec Does this mean that 2.1.0 will not be able to create/delete RBD snapshots at all?
Per the struck out list above, looks like there will not be any snapshot support... Obviously need to know to evaluate the impact to my project.

What is the timeline for v3.0.0? And, given the previous slips, is there a risk that these features might not show up in 3.0 too? I understand this is a complex feature and just trying to get a timeline estimate to plan better on our side.
