      Feature Overview (aka. Goal Summary)  

      An elevator pitch (value statement) that describes the Feature in a clear, concise way.  Complete during New status.

       

      This feature is coming from upstream Kubernetes as Beta, we should have testing and documentation.

       

      Reclaim policy associated with the Persistent Volume is currently ignored under certain circumstance. For a Bound PV-PVC pair the ordering of PV-PVC deletion determines whether the PV delete reclaim policy is honored. The PV honors the reclaim policy if the PVC is deleted prior to deleting the PV, however, if the PV is deleted prior to deleting the PVC then the Reclaim policy is not exercised. As a result of this behavior, the associated storage asset in the external infrastructure is not removed.

      Goals (aka. expected user outcomes)

      The observable functionality that the user now has as a result of receiving this feature. Include the anticipated primary user type/persona and which existing features, if any, will be expanded. Complete during New status.

      Prevent volumes from being leaked by honoring the PV Reclaim policy after the Bound PVC is also deleted.
       

      Requirements (aka. Acceptance Criteria):

      A list of specific needs or objectives that a feature must deliver in order to be considered complete.  Be sure to include nonfunctional requirements such as security, reliability, performance, maintainability, scalability, usability, etc.  Initial completion during Refinement status.

      Ensure reclaim policy is applied regardless of the order in which the PVC & PV are processed.

       

      Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed.  Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.

      Deployment considerations List applicable specific needs (N/A = not applicable)
      Self-managed, managed, or both all
      Classic (standalone cluster) yes
      Hosted control planes yes
      Multi node, Compact (three node), or Single node (SNO), or all all
      Connected / Restricted Network both
      Architectures, e.g. x86_x64, ARM (aarch64), IBM Power (ppc64le), and IBM Z (s390x) all
      Operator compatibility Core - N/A
      Backport needed (list applicable versions) No
      UI need (e.g. OpenShift Console, dynamic plugin, OCM) No
      Other (please specify)  

      Use Cases (Optional):

      Include use case diagrams, main success scenarios, alternative flow scenarios.  Initial completion during Refinement status.

      Questions to Answer (Optional):

      Include a list of refinement / architectural questions that may need to be answered before coding can begin.  Initial completion during Refinement status.

      Out of Scope

      High-level list of items that are out of scope.  Initial completion during Refinement status.

      N/A

      Background

      Provide any additional context is needed to frame the feature.  Initial completion during Refinement status.

      Prevent volumes from being leaked by honoring the PV Reclaim policy after the Bound PVC is also deleted.
       

      Customer Considerations

      Provide any additional customer-specific considerations that must be made when designing and delivering the Feature.  Initial completion during Refinement status.

      This should be transparent to customers/users, no change in the interfaces. Customers should now have their Persistent Volume Reclaim Policy honored  in every cases.

      Documentation Considerations

      Provide information that needs to be considered and planned so that documentation will meet customer needs.  If the feature extends existing functionality, provide a link to its current documentation. Initial completion during Refinement status.

      RN only

      Interoperability Considerations

      Which other projects, including ROSA/OSD/ARO, and versions in our portfolio does this feature impact?  What interoperability test scenarios should be factored by the layered products?  Initial completion during Refinement status.

      Core storage no Interoperability Considerations
