Hi Chris Having also recently started exploring Ceph. I too happened upon this problem. I found that terminating the command witch ctrl-c seemed to stop the looping. Which btw. also happens on all other mgr instances in the cluster. Regards Jens -----Original Message----- From: Chris Read <chris.read@xxxxxxxxx> Sent: 11. januar 2021 21:54 To: ceph-users@xxxxxxx Subject: "ceph orch restart mgr" command creates mgr restart loop Greetings all... I'm busy testing out Ceph and have hit this troublesome bug while following the steps outlined here: https://docs.ceph.com/en/octopus/cephadm/monitoring/#configuring-ssl-tls-for-grafana When I issue the "ceph orch restart mgr" command, it appears the command is not cleared from a message queue somewhere (I'm still very unclear on many ceph specifics), and so each time the mgr process returns from restart it picks up the message again and keeps restarting itself forever (so far it's been stuck in this state for 45 minutes). Watching the logs we see this going on: $ ceph log last cephadm -w root@ceph-poc-000:~# ceph log last cephadm -w cluster: id: d23bc326-543a-11eb-bfe0-b324db228b6c health: HEALTH_OK services: mon: 5
