I had Cassandra cluster of 3 nodes. I was performing some colud migration activity and for that, I added two more nodes in an existing cluster and the result is as follows.

The OWNS field was previously 100% for all nodes and now it shows different numbers so is it like whole 100% data is not on each node and suppose if I take down any node by shutting down Cassandra then is there a risk of data loss?
