Hi Cephers, We have some ceph clusters in 12.2.x version, now we want to use upmap balancer,but when i set set-require-min-compat-client to luminous, it's failed
# ceph osd set-require-min-compat-client luminous Error EPERM: cannot set require_min_compat_client to luminous: 6 connected client(s) look like jewel (missing 0xa00000000200000); 1 connected client(s) look like jewel (missing 0x800000000000000); 1 connected client(s) look like jewel (missing 0x800000000200000); add --yes-i-really-mean-it to do it anyway ceph features "client": { "group": { "features": "0x40106b84a842a52", "release": "jewel", "num": 6 }, "group": { "features": "0x7010fb86aa42ada", "release": "jewel", "num": 1 }, "group": { "features": "0x7fddff8ee84bffb", "release": "jewel", "num": 1 }, "group": { "features": "0x3ffddff8eea4fffb", "release": "luminous", "num": 7 } } and sessions "MonSession(unknown.0 10.10.100.6:0/1603916368 is open allow *, features 0x40106b84a842a52 (jewel))", "MonSession(unknown.0 10.10.100.2:0/2484488531 is open allow *, features 0x40106b84a842a52 (jewel))", "MonSession(client.? 10.10.100.6:0/657483412 is open allow *, features 0x7fddff8ee84bffb (jewel))", "MonSession(unknown.0 10.10.14.67:0/500706582 is open allow *, features 0x7010fb86aa42ada (jewel))" can i use --yes-i-really-mean-it to force enable it ? I know kernel 4.13 is full support with ceph luminous and I know that Redhat backports a lot of things to the 3.10 kernel, So which is the matching version?
