Specifically customer is looking to peer multiple cephfs-mirror sources to a single destination. Currently upon trying to peer a second source the user is getting "Error EEXIST: already an active peer". Apparently a "fan out" configuration is currently being developed upstream. This request is more the inverse of a "fan out" which is a single source to many destinations. Again, this is to support multiple destinations on a single source in more of a consolidation or archival configuration.
