Joe, The disks are 9TB drives, with over 3Tb available. This is true for each node Ideally, we would be able to replay up to 12 hours for any of the flows in order to troubleshoot/investigate data issues.

That means we will work to remove content no longer reachable in the flow until we are at 50% of the available disk space for that volume. So how big is the disk there for each node? Can you share more about what you are hoping to see happen against what is happening?

All others when trying to view NiFi Data Provenance -> Content will show Replay Content is no longer available in Content Repository Checking all 3 nodes at intervals, the content repository size on disk is: Node 1: 1.1G, goes up to 2.1G, back down to 1.1G.
