Jeremy Hanna commented on CASSANDRA-6320:
-----------------------------------------

After that DC was balanced, nodetool ring showed the correct number of replicas, matching the keyspace metadata again.

> There are two datacenters and the keyspace configuration for this keyspace is set to 3 in each datacenter.  During a rebalance of the ring, during the range movements, nodetool ring <keyspace> is reporting that 2 replicas are in the datacenter where movement is occurring.
> NodeCmd calls StorageService.effectiveOwnership which seems like it should be definitive in terms of calculating the number of replicas.  Then NodeCmd.printRing goes through that and takes each filtered list of datacenters and prints each with replica and node information via NodeCmd.printDc.
> Hopefully it's just a corner case bug in the reporting itself, but I thought I would log this in case there was a corner case with the actual ownership during range movements.  Also the range movements could be a red herring that is just coincidental to this problem.
