Dear All,


I am in a need of assistance on having Persistent Storage for our
OpenShift(Origin) 3.9;  Here are more details: 10 VMs in total -  3 Masters
+ 7 nodes.

Plan is to have redundant storage solution for our containerized apps and
infrastructure components such as Registry (RWX ReadWriteMany), Aggregated
Logging, Metrics.

For future we might need RWX also for our apps which leads me to use
RedHat's GlusterFS.



So far have been researching for Container-Ready Storage
<https://access.redhat.com/documentation/en-us/container-native_storage/3.9/
html/container-native_storage_for_openshift_container_platform/chap-document
ation-introduction_crs_for_ocp> . From the docs I got that it has to be
deployed on separate Origin environment for managing it.  Please correct me
if I am wrong.



Difference with Container-Native Storage
<https://access.redhat.com/documentation/en-us/container-native_storage/3.9/
html/container-native_storage_for_openshift_container_platform/chap-document
ation-red_hat_gluster_storage_container_native_with_openshift_platform-rhgs_
container_converged_with_os>  is that here the Storage services are deployed
in the same Origin cluster where our applications are.



Please help me decide which of both solutions to test and go for.

Also would be much of help if you can share with me reference documentation
about the Container-Native/Ready storage as the one for Openshift Advanced
installation. Would be helpful to see steps and considerations taken during
the setup.



Goal is to have everything done by automation such as Ansible or other
means, so any thoughts here are also welcomed.



With Regards,
