Fixed In Version: ceph-19.2.0-2.el9cp
Doc Type: Bug Fix
Doc Text:
Cause: The pg_upmap_primary structure was not properly exposed in Ceph features. Consequence: Users who ran `ceph osd set-require-min-compat-client reef` prior to using pg_upmap_primary (this is required, as it is only available in reef) were able to reset back to an older client even after pg_upmap_primary was still in use. This could mean that older clients might connect to the cluster and be unable to interpret the pg_upmap_primary structure. Fix: The pg_upmap_primary structure was properly exposed in Ceph features so it is glued to the SERVER_REEF feature bit. Result: Users can now no longer change require-min-compat-client to a lower version than Reef if pg_upmap_primary is in use, ensuring that only Reef clients may connect.
