Description of problem (please be detailed as possible and provide log snippests): ODF 4.17 was supposed to ship with Ceph 8 (Squid) where bluestore-rdr changes were merged back to bluestore. This meant that ODF would need to migrate the bluestore-rdr OSD back to bluestore. Now ODF 4.17 won't be shipped with Ceph 8 (Squid) and will use Ceph 7 (reef). So ODF should not migrate bluestore-rdr OSDS. Version of all relevant components (if applicable): Does this issue impact your ability to continue to work with the product (please explain in detail what is the user impact)? Is there any workaround available to the best of your knowledge? Rate from 1 - 5 the complexity of the scenario you performed that caused this bug (1 - very simple, 5 - very complex)? Can this issue reproducible? Can this issue reproduce from the UI? If this is a regression, please provide more details to justify this: Steps to Reproduce: 1. Upgraded RDR optimised cluster from 4.16 to 4.17 Actual results: bluestore-rdr OSD migrates to bluestore Expected results: No migration should take place. ODF should continue using OSDs based on Bluestore-rdr. No regression impact of this change should be there. Additional info:
