Hi Rafael, I would not force the min_compat_client to be reef when there are still luminous clients connected, as it is important for all clients to be >=Reef to understand/encode the pg_upmap_primary feature in the osdmap.
As for checking which processes are still luminous, I am copying @Radoslaw Zarzynski <[email protected]> who may be able to help more with that.
