Hi. There is some news regarding two-cluster replication ? I would like to use it in a DR scenario, with the big cluster that can have some VMs replicated on a small one (but different, and possibly in a different datacenter).
Something included in the proxmox gui will be really great and add a lot of value to proxmox itself.
