The above appears to have worked for 4 out of 5 mgr daemons - but now most "ceph orch" commands give me the error "Error ENOENT: Module not found". I can also see many cephadm-related "module not found" error in system logs. Update a few minutes later: have updated the last mgr + all the mons to 20.2.0 by manually updating the container image in their respective unit.run files. Now all ten daemons are on stable Tentacle and the Ceph cluster seems happy - but cephadm still doesn't work. -- MS _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected] This message and its attachments are from Data Dimensions and are intended only for the use of the individual or entity to which it is addressed, and may contain information that is privileged, confidential, and exempt from disclosure under applicable law.
