[ovirt-users] oVirt DR: ansible with 4.1, only a subset of storage domain replicated

Hello, i'm starting the implementation of our disaster recovery site with RHV 4.1.latest for our production environment. Our production setup is very easy, with self hosted engine on dc KVMPDCA, and virtual machines both in KVMPDCA and KVMPD dcs. All our setup has an FC storage backend, which is EMC VPLEX/VMAX in KVMPDCA and EMC VNX8000. Both storage arrays supports replication via their own replication protocols (SRDF, MirrorView), so we'd like to delegate to them the replication of data to the remote site, which is located on another remote datacenter. In KVMPD DC we have some storage domains that contains non critical VMs, which we don't want to replicate to remote site (in case of failure they have a low priority and will be restored from a backup). In our setup we won't replicate them, so will be not available for attachment on remote site. Can be this be an issue? Do we require to replicate everything? What about master domain? Do i require that the master storage domain stays on a replicated volume or can be any of the available ones? I've seen that since 4.1 there's an API for updating OVF_STORE disks. Do we require to invoke it with a frequency that is the compatible with the replication frequency on storage side. We set at the moment RPO to 1hr (even if planned RPO requires 2hrs). Does OVF_STORE gets updated with the required frequency? I've seen a recent presentation by Maor Lipchuk that is showing the automagic ansible role for disaster recovery: -- "E' assurdo impiegare gli uomini di intelligenza eccellente per fare calcoli che potrebbero essere affidati a chiunque se si usassero delle macchine" Gottfried Wilhelm von Leibnitz, Filosofo e Matematico (1646-1716) "Internet è la più grande biblioteca del mondo.
