Anurag Parvatikar reassigned HDDS-17527:
----------------------------------------
Assignee: Anurag Parvatikar
> Migrate Storage Policy to the post-ZDU OM component-version framework
> ---------------------------------------------------------------------
>
> Key: HDDS-17527
> URL: https://issues.apache.org/jira/browse/HDDS-17527
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: Ozone Manager
> Reporter: Devesh Kumar Singh
> Assignee: Anurag Parvatikar
> Priority: Major
>
> After merging upstream ZDU into HDDS-11233, remove the feature-specific
> BUCKET_STORAGE_POLICY_SUPPORT(12) registration from legacy OMLayoutFeature
> and introduce it at the next available, nonconflicting OzoneManagerVersion
> value. Migrate callers, upgrade actions, initialization and tests to the
> post-ZDU version manager. Audit persisted VERSION and DB apparent-version
> handling for feature-branch environments that may have finalized legacy
> layout 12; document whether migration or test-cluster reinitialization is
> required. Preserve historic layout IDs and upstream version sequencing.
> *Why a gate is needed:* The OM apparent version is the server-side authority
> for whether new policy metadata may be persisted. A wrong enum sequence can
> enable the feature early, make startup fail, or break downgrade safety.
> *Acceptance criteria:* Correct new enum and ordering; no stale
> feature-specific layout references; old supported apparent versions load;
> version-12 compatibility decision recorded; tests cover nextVersion,
> isAllowed, finalization, persistence and restart. Source anchors:
> OzoneManagerVersion, OMVersionManager, OMLayoutFeature.
