Ceph Dashboard is now available at:

URL: https://rpi-iot-jsho-ceph-01:8443/
User: admin
Password: <password>

Enabling client.admin keyring and conf on hosts with „admin“ label
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 3ece5414-f716-11ee-adce-dca632593fcd -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

For more information see:

https://docs.ceph.com/en/pacific/mgr/telemetry/

Bootstrap complete.
