Indexer Cluster Replication Question

Hello!

I am looking for your help. I have 2 indexer nodes in a splunk indexer cluster with rf=2 and sf=2 and we want to add 2 more nodes to this site, I only have one virtual site. I need your help because I want to update the rf to 3.
So by adding a new node and updating the rf, the historical data from the 2 oldest nodes will be replicated to the new nodes to meet the replication factor?

Hi @aaronhernandez,

yes, for my knowledge the old replicated data will be replicated to more indexers when you add more peers and you change the Replication Factor.

it's the same situation that you have when you have a down server.

The only requirement is that those indexes are in alredy in replication so the buckets are already replicated between peers.

It's different if you have not replicated old data that's not possible to replicate, e.g. when you create the cluster from two stand alone Indexers the old data aren't replicated.

Ciao.
