Thanks.
SolrCloud will determine what nodes/cores are available by looking at the clusterstate. The clusterstate might be indicating that all replicas are down for one or more shards in your collection. Exactly where the clusterstate lives in zookeeper will depend on what version you are running and whether your collections on this cloud were ever handled by 4.x versions of Solr. Legacy collections will have their clusterstate in /clusterstate.json, newer collections created by 5.x will have /collections/xxxx/state.json, where xxxx is the name of the collection. These are zookeeper paths, not filesystem paths. Thanks, Shawn
