You can simply create a new SolrCore with the same collection and shard id as the colleciton and shard you want to add a replica too.
There is also an addReplica command comming to the collections API. Or perhaps it’s in 4.7, I don’t know, this JIRA issue is a little confusing as it’s still open, though it looks like stuff has been committed: https://issues.apache.org/jira/browse/SOLR-5130 -- Mark Miller about.me/markrmiller On March 12, 2014 at 10:40:15 AM, Mike Hugo (m...@piragua.com) wrote: After a collection has been created in SolrCloud, is there a way to modify the Replication Factor? Say I start with a few nodes in the cluster, and have a replication factor of 2. Over time, the index grows and we add more nodes to the cluster, can I increase the replication factor to 3? Thanks!
