All, we are moving our PoC clusters to openshift 3.9. Being nfs deemed not production grade we are considering moving to glusterfs.
Our preference is toward having possibly one centralized glusterfs cluster serving multiple openshift clusters with dynamic volume provisioning. This is to lower both number of moving parts and number of VMs reserved for gluster operations. We have read relevant documentation: https://docs.openshift.org/3.9/install_config/persistent_storage/persistent_storage_glusterfs.html and have few doubts. >From what we see, Container Native Storage (CNS) or Container Ready Storage (CRS) are requiring a number of 3 VMs (actually 6 separating infra volumes from app volumes) per openshift cluster. - Is there a way to share gluster VMs among several openshift cluster for e.g. CRS? >From what we read, the answer seems to be a no. In this case, we'll probably move to a standalone glusterfs cluster with heketi. The best would be to have this with openshift/kubernetes orchestration for storage services (e.g. https://github.com/gluster/gluster-kubernetes). - Has anyone done this already and could suggest ansible playbooks that do/facilitate the job? - Are there possible limitations when compared with CRS or CNS solutions? Thanks for any help, -m
