Hello, I've now cluster healthy. I've studied OSDMonitor.cc file and I've found, that there is some problematic logic. Assumptions: 1) require_osd_release can be only raise. 2) ceph-mon in version 17.2.3 can set require_osd_release to minimal value 'octopus'. I have two variants: 1) If I can set require_osd_release to octopus, I have to have set require_osd_release actually to 'nautilus' (I will raise require_osd_release from nautilus to octopus). Then I have to have on line 11618 in OSDMonitor.cc this line: ceph_assert(osdmap.require_osd_release >= ceph_release_t::nautilus); 2) If I would have to preserve on line 11618 in file OSDMonitor.cc line: ceph_assert(osdmap.require_osd_release >= ceph_release_t::octopus); it is nonsense to can set require_osd_release parameter to 'octopus', because this line ensures, that I alredy set require_osd_release parameter to octopus. I suggest to use variant 1) and I've sendig attached patch. There is another question, if MON daemon have to check require_osd_release, when it is joining to the cluster, when it cannot raise it's value. It is potentially dangerous situation, see my old e-mail below...
