I am running Splunk 6.1, using Search Head Pooling. Our search heads currently search indexers that are clustered. I have a customer who wants to have the ability to search their own search peer via my search head, but their indexer is not clustered. Can I mix and match without any issues?
Should be no issue at all. Just add the other peers (indexers) as Search Peers in the Distributed Search menu. You'll notice the clustered indexers are already defined in there as a result of being a search head for the cluster.
