What are the plans for getting this mount propagation feature to beta status in 1.9? Will it be available without a feature gate in 1.9? The Rook team would love to start using this feature by default as soon as possible.

I don't see it tracked in the SIG Storage 1.9 planning sheet, should it be tracked there? https://docs.google.com/spreadsheets/d/1t4z5DYKjX2ZDlkTpCnp18icRAQqOE85C1T1r2gqJVck/edit?usp=sharing

It's planned for 1.10, volunteers needed. We need more tests:

  • Together with CSI.
  • Check various recent and "long-term support" distros.
  • Add Kubernetes e2e tests for existing in-tree volume plugins (Gluster, Ceph, ...) using containerized mount utilities - this will stress test it quite a lot.

@saad-ali, shall we bake it as Beta for one more release and have it stable in 1.12?

@jsafrane I'll tentatively set this to next-milestone, but if you feel differently, just let us know.

Hey there! @saad-ali I'm the wrangler for the Docs this release. Is there any chance I could have you open up a docs PR against the release-1.12 branch as a placeholder? That gives us more confidence in the feature shipping in this release and gives me something to work with when we start doing reviews/edits. Thanks! If this feature does not require docs, could you please update the features tracking spreadsheet to reflect it?
