Just found out that we have some strangler osds running ceph 14:
{ "mon": { "ceph version 15.2.16 (d46a73d6d0a67a79558054a3a5a72cb561724974) octopus (stable)": 3 }, "mgr": { "ceph version 15.2.16 (d46a73d6d0a67a79558054a3a5a72cb561724974) octopus (stable)": 3 }, "osd": { "ceph version 14.2.21 (5ef401921d7a88aea18ec7558f7f9374ebd8f5a6) nautilus (stable)": 47, "ceph version 15.2.16 (d46a73d6d0a67a79558054a3a5a72cb561724974) octopus (stable)": 225 }, "mds": {}, "rgw": { "ceph version 15.2.16 (d46a73d6d0a67a79558054a3a5a72cb561724974) octopus (stable)": 1 }, "overall": { "ceph version 14.2.21 (5ef401921d7a88aea18ec7558f7f9374ebd8f5a6) nautilus (stable)": 47, "ceph version 15.2.16 (d46a73d6d0a67a79558054a3a5a72cb561724974) octopus (stable)": 232 } }
We should upgrade those in nautilus little by little.
