Good job! More IPv6 is better :) > Question is, will RBD mirroring still be possible between the two?

See the ceph-conf documentation for how to configure multiple clusters." So, in 'remote.conf' you can add the IPv6 addresses of a cluster running on IPv6 and on 'ceph.conf' the IPv4 addresses. The rbd-mirror daemon will eventually talk to librbd/librados which will act as a 'proxy' between the two clusters. I think it works, but that's just based on reading the docs and prior knowledge.
