Ceph Dashboard is now available at:

             URL: https://rvmdocker01.rvmgroup.local:8443/
            User: admin

Enabling client.admin keyring and conf on hosts with "admin" label
Saving cluster configuration to /var/lib/ceph/3e8ba254-3b1d-11ef-8727-bc2411117fd0/config directory
Enabling autotune for osd_memory_target
You can access the Ceph CLI as following in case of multi-cluster or non-default config:

        sudo /usr/sbin/cephadm shell --fsid 3e8ba254-3b1d-11ef-8727-bc2411117fd0 -c /etc/ceph/ceph.conf -k /etc/ceph/ceph.client.admin.keyring

Or, if you are only running a single cluster on this host:

        sudo /usr/sbin/cephadm shell 

Please consider enabling telemetry to help improve Ceph:

        ceph telemetry on

ssh-copy-id -f -i /etc/ceph/ceph.pub root@rvmdocker02
scp /etc/hosts rvmdocker02:/etc/hosts
scp /etc/ceph/ceph.conf rvmdocker02:/etc/ceph/ceph.conf
scp /etc/ceph/ceph.client.admin.keyring rvmdocker02:/etc/ceph/ceph.client.admin.keyring
