Hi, Sorry for very late response, but i was sick. Our case is to make a failover rbd instance in another cluster. We are storing block device images, for some services like Database. We need to have a two clusters, synchronized, for a quick failover, if first cluster goes down, or for upgrade with restart, or many other cases. Volumes are in many sizes: 1-500GB external block device for kvm vm, like EBS.
