[ceph-users] feature_map differs across mon_status

Just curious why the feature_map portions differ in the return of mon_status across a cluster. Below is an example from each of five mons in a healthy 16.2.10 cephadm cluster: root@mon.d:~# ceph tell mon.a mon_status | jq .feature_map { "mon": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 1 } ], "osd": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 42 } ], "client": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 1 } ], "mgr": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 1 } ] } root@mon.d:~# ceph tell mon.b mon_status | jq .feature_map { "mon": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 1 } ], "osd": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 36 } ], "client": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 2 } ] } root@mon.d:~# ceph tell mon.c mon_status | jq .feature_map { "mon": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 1 } ], "osd": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 81 } ], "client": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 4 } ], "mgr": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 2 } ] } root@mon.d:~# ceph tell mon.d mon_status | jq .feature_map { "mon": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 1 } ], "osd": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 112 } ], "client": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 7 } ] } root@mon.d:~# ceph tell mon.e mon_status | jq .feature_map { "mon": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 1 } ], "osd": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 88 } ], "client": [ { "features": "0x3f01cfb9fffdffff", "release": "luminous", "num": 4 } ] }
