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.

Subject: [Openstack] Replication count change on running 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.
