I agree--especially for someone somewhat unfamiliar with containers.
cephadm sets up binds mounts and log rotation for the host /var/log/ceph
into the container, but by default logging is done the containery way by
just writing to stderr where it is picked up by journald. You can switch
to traditional log files with 'ceph config set global log_to_file true'.
