Hi, We are seeing the mgr attempt to apply our OSD spec on the various hosts, then block. When we investigate, we see the mgr has executed cephadm calls like so, which are blocking: root 1522444 0.0 0.0 102740 23216 ? S 17:32 0:00 \_ /usr/bin/python3 /var/lib/ceph/XXXXX/cephadm.30cb78bdbbafb384af862e1c2292b944f15942b586128e91262b43e91e11ae90 --image docker.io/ceph/ceph@sha256:694ba9cdcbe6cb7d25ab14b34113c42c2d1af18d4c79c7ba4d1f62cf43d145fe ceph-volume --fsid XXXXX -- lvm list --format json This occurs on all hosts in the cluster, following starting/restarting/failing over a manager. It's blocking an in-progress upgrade post-manager updates on one cluster, currently. Looking at the cephadm logs on the host(s) in question, we see the last entry appears to be truncated, like: 2021-05-10 17:32:06,471 INFO /usr/bin/podman: "ceph.db_uuid": "1n2f5v-EEgO-1Kn6-hQd2-v5QF-AN9o-XPkL6b", 2021-05-10 17:32:06,471 INFO /usr/bin/podman: "ceph.encrypted": "0", 2021-05-10 17:32:06,471 INFO /usr/bin/podman: "ceph.osd_fsid": "XXXX", 2021-05-10 17:32:06,471 INFO /usr/bin/podman: "ceph.osd_id": "205", 2021-05-10 17:32:06,471 INFO /usr/bin/podman: "ceph.osdspec_affinity": "osd_spec", 2021-05-10 17:32:06,471 INFO /usr/bin/podman: "ceph.type": "block", The previous entry looks like this: 2021-05-10 17:32:06,469 INFO /usr/bin/podman: "ceph.db_uuid": "TMTPD5-MLqp-06O2-raqp-S8o5-TfRG-hbFmpu", 2021-05-10 17:32:06,469 INFO /usr/bin/podman: "ceph.encrypted": "0", 2021-05-10 17:32:06,469 INFO /usr/bin/podman: "ceph.osd_fsid": "XXXX", 2021-05-10 17:32:06,469 INFO /usr/bin/podman: "ceph.osd_id": "195", 2021-05-10 17:32:06,470 INFO /usr/bin/podman: "ceph.osdspec_affinity": "osd_spec", 2021-05-10 17:32:06,470 INFO /usr/bin/podman: "ceph.type": "block", 2021-05-10 17:32:06,470 INFO /usr/bin/podman: "ceph.vdo": "0" 2021-05-10 17:32:06,470 INFO /usr/bin/podman: }, 2021-05-10 17:32:06,470 INFO /usr/bin/podman: "type": "block", 2021-05-10 17:32:06,470 INFO /usr/bin/podman: "vg_name": "ceph-ffd1a4a7-316c-4c85-acde-06459e26f2c4" 2021-05-10 17:32:06,470 INFO /usr/bin/podman: } 2021-05-10 17:32:06,470 INFO /usr/bin/podman: ], We'd like to get to the bottom of this, please let us know what other information we can provide.
