The reason that this happened is because you've got two nodes running on every server. From SolrCloud's perspective, there are ten distinct nodes, not five. SolrCloud doesn't notice the fact that different nodes are running on the same server(s). If your reaction to hearing this is that it *should* notice, you're probably right, but in a typical use case, each server should only be running one Solr instance, so this would never happen. There is only one instance where I can think of where I would recommend running multiple instances per server, and that is when the required heap size for a single instance would be VERY large. Running two instances with smaller heaps can yield better performance. See this issue: https://issues.apache.org/jira/browse/SOLR-6027 Thanks, Shawn
