I have cloned BZ1488366 as a docs bug because the resolution to BZ1488366 needs to be included in the docs, as well. This is for all versions of OpenShift (or, at least, 3.7+). The resolution of BZ1488366 was to add the following text to the example inventory file that is shipped with the openshift RPMs (in 3.7, /usr/share/doc/openshift-ansible-docs-3.7.0/docs/example-inventories/hosts.example): # nfs_directory must conform to DNS-1123 subdomain must consist of lower case # alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character #openshift_hosted_registry_storage_nfs_directory=/exports This requirement is still the case in 3.11, but it is not in the documentation at all, so customers who are not specifically looking at the example inventory files shipped with the RPMs (which is probably most of them) will not see this. I will leave it up to the professionals on how/where to do this, but the following sections are where we may want to start with this sort of information: https://docs.openshift.com/container-platform/3.11/install/configuring_inventory_file.html#advanced-install-cluster-metrics-storage https://docs.openshift.com/container-platform/3.11/install/configuring_inventory_file.html#advanced-installation-logging-storage https://docs.openshift.com/container-platform/3.11/install/configuring_inventory_file.html#advanced-install-registry-storage https://docs.openshift.com/container-platform/3.11/install/configuring_inventory_file.html#configuring-oab-storage
