Hey, I'm using solr 5.2.1 and yesterday I started migrating to SolrCloud so I might be quite noobish with it. The thing is that I could create 3 collections with not so many inconvenients, but when trying to create another collection it throws a timeout and inside solr log it says "Could not get shard id for core my_core_shard1_replica1".
My SolrCloud has three servers running zookeeper and two of them running solr in cloud mode. The command for creating the collection is: http://localhost:8983/solr/admin/collections?action=CREATE&name=my_core&numShards=1&maxShardsPerNode=1&collection.configName=my_core_config&createNodeSet=server1:8983_solr Thanks.
