HI!
I've been playing with dual site openstack clouds. I use ceph as a backend for
Cinder volumes. Each openstack has its own ceph cluster. Data replication
is done by ceph rbd mirroring.
Current Cinder replication design (cheesecake) only protects against
storage failure.
What about support for multi site deployments and protection of whole
data center.
Has any work been planned or done yet on that topic?
