Thanks David, Spent some more time digging in the logs/google. Also had a further 2 nodes fail this morning (different nodes). Looks like it’s related to apt-auto updates on Ubuntu 20.04, although we don’t run unattended upgrades. Docker appears to get a terminate signal which shutsdown/restarts all the containers but some don’t come back cleanly. There’s was also some legacy unused interfaces/bonds in the netplan config. Anyway, cleaned all that up...so hopefully it’s resolved. Cheers, A.

On my containerized setup, the services that cephadm created are: dcaro@node1:~ $ sudo systemctl list-units | grep ceph ceph-d49b287a-b680-11eb-95d4-e45f010c03a8@crash.node1.service loaded active running Ceph crash.node1 for d49b287a-b680-11eb-95d4-e45f010c03a8 ceph-d49b287a-b680-11eb-95d4-e45f010c03a8@mgr.node1.mhqltg.service loaded active running Ceph mgr.node1.mhqltg for d49b287a-b680-11eb-95d4-e45f010c03a8 ceph-d49b287a-b680-11eb-95d4-e45f010c03a8@mon.node1.service loaded active running Ceph mon.node1 for d49b287a-b680-11eb-95d4-e45f010c03a8 ceph-d49b287a-b680-11eb-95d4-e45f010c03a8@osd.3.service loaded active running Ceph osd.3 for d49b287a-b680-11eb-95d4-e45f010c03a8 ceph-d49b287a-b680-11eb-95d4-e45f010c03a8@osd.7.service loaded active running Ceph osd.7 for d49b287a-b680-11eb-95d4-e45f010c03a8 system-ceph\x2dd49b287a\x2db680\x2d11eb\x2d95d4\x2de45f010c03a8.slice loaded active active system-ceph\x2dd49b287a\x2db680\x2d11eb\x2d95d4\x2de45f010c03a8.slice ceph-d49b287a-b680-11eb-95d4-e45f010c03a8.target loaded active active Ceph cluster d49b287a-b680-11eb-95d4-e45f010c03a8 ceph.target loaded active active All Ceph clusters and services where the string after 'ceph-' is the fsid of the cluster.

As in, if you execute this journalctl outside of the container it will not find anything of course. > > > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx -- David Caro SRE - Cloud Services Wikimedia Foundation <https://wikimediafoundation.org/> PGP Signature: 7180 83A2 AC8B 314F B4CE 1171 4071 C7E1 D262 69C3 "Imagine a world in which every single human being can freely share in the sum of all knowledge.
