• If you have ceph-mon and ceph-mgr services (on Controllers by default) that do not have the docker systemd service dependency, run the following command to verify whether the systemd services include dependency(Requires option):

grep -i "Requires=docker.service" /etc/systemd/system/ceph-m*\@.service
