.New support for topographical labeling on hosts This enhancement expands cephadm’s capabilities by introducing topological key/value properties for hosts. Administrators can now group hosts by meaningful, configurable labels, enabling more efficient rolling upgrades. Instead of issuing multiple commands for each service group (for example, distinct RGW services by rack), upgrades can iterate through a list of topographical labels—streamlining multi-rack operations. Additionally, these new properties open the door for enhanced RADOS read affinity by leveraging improved CRUSH location settings.
