What are you doing to clean zk? You should be able to simply use the ZkCli clear cmd:
http://wiki.apache.org/solr/SolrCloud#Command_Line_Util Just make sure you stop your Solr instances before clearing it. Clearing out zk from under a running Solr instance is not a good thing to do. This should be as simple as, stop your Solr instances, use the clean command on / or /solr (whatever the root is in zk for you Solr stuff), start your Solr instances, create the collection again. - Mark On Apr 25, 2013, at 11:27 AM, Furkan KAMACI <furkankam...@gmail.com> wrote: > I have a Zookeepeer ensemble with three machines.
