Hi List, Trying to learn Ceph, so I'm using a Vagrant setup of six nodes with Docker and LVM on them. But as soon as I reach this step https://docs.ceph.com/docs/master/cephadm/#bootstrap-a-new-cluster I get stuck with this error: ``` INFO:cephadm:Mgr epoch 5 not available, waiting (6/10)... INFO:cephadm:Non-zero exit code 22 from /bin/docker run --rm --net=host -e CONTAINER_IMAGE=docker.io/ceph/daemon-base:latest-master-devel -e NODE_NAME=monitor01 -v /var/log/ceph/114dc730-66ca -11ea-b6f9-5254008afee6:/var/log/ceph:z -v /tmp/ceph-tmpbrsg0raa:/etc/ceph/ceph.client.admin.keyring:z -v /tmp/ceph-tmpq7q4mc5h:/etc/ceph/ceph.conf:z --entrypoint /usr/bin/ceph docker.io/ceph /daemon-base:latest-master-devel tell mgr mgr_status INFO:cephadm:/usr/bin/ceph:stderr no valid command found; 10 closest matches: INFO:cephadm:/usr/bin/ceph:stderr 0 INFO:cephadm:/usr/bin/ceph:stderr 1 INFO:cephadm:/usr/bin/ceph:stderr 2 INFO:cephadm:/usr/bin/ceph:stderr abort INFO:cephadm:/usr/bin/ceph:stderr assert INFO:cephadm:/usr/bin/ceph:stderr config diff INFO:cephadm:/usr/bin/ceph:stderr config diff get <var> INFO:cephadm:/usr/bin/ceph:stderr config get <var> INFO:cephadm:/usr/bin/ceph:stderr config help [<var>] INFO:cephadm:/usr/bin/ceph:stderr config set <var> <val>...

Also the "/var/log/ceph/114dc730-66ca-11ea-b6f9-5254008afee6" folder is empty, no logs. I must admit I'm stumped, I don't really know where to go from here. Any pointers for me perhaps? Thanks! Mark
