> Project: Apache Ozone
> Issue Type: Sub-task
> Components: Ozone Manager
> Reporter: Aravindan Vijayan
> Assignee: Ethan Rose
> Priority: Blocker
>
> HDDS-2939 makes fundamental changes to how OM writes & reads its metadata.
> Since this is about as big a layout change as can be, we have to make sure
> this is properly managed through the upgrade flow. In addition to upgrades,
> we should support downgrades from pre-finalized state of OM.
> Individual Work Items
> * An un-finalized OM cannot allow a client to create FSO based buckets.
> * Default layout is O_S / LEGACY_FS in un-finalized & FSO post finalization)
> * An explicit request to crate FSO bucket pre-finalization should fail.
> * Add acceptance or integration test to capture the above.
