@Stefan Did you find any solution to your problem? I just got the same error ... I have a running pacific cluster with 4x monitor servers and wanted to join a fifth monitor via docker container. My container start command is: docker run --name ceph-mon-arbiter01 --net=host -v /etc/ceph:/etc/ceph -v /var/lib/ceph/:/var/lib/ceph/ -e MON_IP=192.168.2.5 -e CEPH_PUBLIC_NETWORK=192.168.2.0/24 quay.io/ceph/daemon:latest-pacific mon This works for the first time - then if i stop the container and start it again i just geht the following output: 2022-06-17 14:47:41 /opt/ceph-container/bin/entrypoint.sh: Existing mon, trying to rejoin cluster... After that, the container exits. If i manually delete /var/lib/ceph/mon/ceph-arbiter01/ then the container is starting again.
