Description

Testing and any documentation to enable RHOSO support for the Ceph-9 release (RHCS9) as an external ceph cluster to enable customers on the latest RHCS major release.

• RHCS 9 GA was Oct 22 2025
• https://productpages.redhat.com/ceph-9-0/schedule/tasks/ 

Goals:

• Produce Internal doc on the process for bumping major release version
• Update upstream/pre-testing to validate ceph9
  • upstream: change upstream operator CI, and devstack-plugin-ceph to upstream T (aka ceph 9)
  • downstream: change at least 1 job to use ceph 9
• Provide any required RHOSO documentation for RHCS9 support

Documentation Considerations

• We may have known limitations (needs downstream ceph ga bits first and verify state), but we may need to allow support without Manila/CephFS initially
• Need to confirm there are not other needs for RHOSO documentation with RCHS9 and that it doesn't impact existing coverage of Ceph configuration or features like adoption.
• Greenfield support note
• RGW + TLS notes
• Ganesha limitation (possible)

Accept Criteria

• Enable Official support for RHCS-9
• MVP is RBD block support
• Upstream and downstream test coverage is sufficient for regression coverage with the new release

Testing considerations:

• Current testing matrix integration:
  • rhoso 18 greenfield: gamma 7, delta (ganesha+rgw) 8, epsilon (cinder) 7
  • rhoso 18 adoption: gamma 7
• Component level : cinder+glance at 7
• considerations:
  • bump delta to 9
  • gamma greenfield to 8
  • epsilon greenfield to 8
  •  

Open Questions

• If Manila or RGW not ready, do we release like last time with what's ready and follow up?
  • Yes - would need to create a seperate initiative to cover as needed

• Do we have any dependencies on the Production RA for CI or ceph client changes?
  • No, we keep client at 7 and we plan the update to 9 for 19
• Do we need a support enablement EPIC for RHCS9 specifically?
• Do we want to make the DOC epic more generic and capture any future needs there too?
  • we can make the doc epic more generic and have stories for RGW, known issues and potential limitations
