Standalone ceph doesn't support the use of ceph deployed on RHCOS nodes so not sure why this part is in here Reported by: rhn-support-kelwhite https://access.redhat.com/documentation/en-us/red_hat_openshift_data_foundation/4.10/html/deploying_openshift_data_foundation_in_external_mode/overview-of-deploying-in-external-mode_rhodf#annotations:7445982e-52aa-49c1-a2ef-20fa37b27576
docs says ``` For instructions regarding how to install a RHCS 4 cluster, see Installation guide. Follow these steps to deploy OpenShift Data Foundation in external mode: If you use Red Hat Enterprise Linux hosts for worker nodes, Enable file system access for containers. Skip this step if you use Red Hat Enterprise Linux CoreOS (RHCOS) hosts. ``` -------> worker node means OCP cluster. looks docs are fine
