Yes, it is possible to change the replica count on a running system. You need to modify the replica count of the existing ring and deploy it to your system. This does not clear existing data in the cluster.

Hi, Is it possible to change the ring replication count for a cluster which is already running, and has data? From what I read, I'll need to recreate the rings with new replication count. But this will clear all my existing data in the cluster. Right? Thanks in advance for the replies. -- -Shyam
