Deployment Architecture

Is it possible to disable replication to specific peers in the cluster?

I've read on peers going into detention status due to storage capacity restrictions, however, is it possible to manually place a peer in detention status so that the data present on it remains searchable but it no longer receives replicated data from the rest of the cluster?

In Splunk Version 6.3 and above Splunk has added capability to Put Cluster Peer in detention. Once Peer is in detention it will no longer get replicated buckets from other peer in cluster.

The command to put cluster peer in detention is
curl -k -u admin:changeme https://SLAVE:MGMT_PORT/services/cluster/slave/control/control/set_detention_override -d value=true -X POST

Is this a command that can be used prior to 6.3 (such as version 6.2.6)?

You can remove the indexer/peer where you don't want replication from the indexer cluster and add that indexer as regular/non-clustered search peer so that it's searchable. See these links.
