I wonder why nodetools don't know the percentage of the ring handeld by my node...

I created this keyspace with

CREATE KEYSPACE mykeyspace WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '3'} AND durable_writes = true;

when nodetool status

Someone has a clue?

Do you get this at the bottom?

Note: Non-system keyspaces don't have the same replication settings, effective ownership information is meaningless

Do you have an opscenter / other keyspaces with different replication settings? In which case, ownership is "meaningless", and what you get is a ?
