Looks like you're using your root partition for docker volume storage (and
thus Elasticsearch storage). That is the default configuration, but not a
recommended one - we recommend specifying storage specifically for docker
https://docs.openshift.org/latest/install_config/install/prerequisites.html#configuring-docker-storage
Also ES data will keep getting blown away if you don't give it a persistent
volume, but hopefully that was already evident to you.
