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 <rzarzyns@redhat.com> who may be able to help more with that.

Hi, I just did a new Ceph installation and would like to enable the "read balancer". However, the documentation requires that the minimum client version be reef. I checked this information through "ceph features" and came across the situation of having 2 luminous clients. # ceph features { "mon": [ { "features": "0x3f03cffffffdffff", "release": "squid", "num": 2 } ], "mds": [ { "features": "0x3f03cffffffdffff", "release": "squid", "num": 2 } ], "osd": [ { "features": "0x3f03cffffffdffff", "release": "squid", "num": 38 } ], "client": [ { "features": "0x2f018fb87aa4aafe", "release": "luminous", "num": 2 }, { "features": "0x3f03cffffffdffff", "release": "squid", "num": 5 } ], "mgr": [ { "features": "0x3f03cffffffdffff", "release": "squid", "num": 2 } ] }
I tryed to configure the minimum version to reef and received the following alert: # ceph osd set-require-min-compat-client reef Error EPERM: cannot set require_min_compat_client to reef: 2 connected client(s) look like luminous (missing 0x80000000); add --yes-i-really-mean-it to do it anyway
Is it ok do confirm anyway? Which processes are still as luminous?
