Hi: I have a single node Elasticsearch instance running (version 1.0.0). This instance was configured with multicast false and no unicast IPs specified. and I change the default ports from 9200,9300 to 9600,9700 with 5 Shards and no replication. I just added a new node to this instance like so : on a new server, I used the same exact Elasticsearch version, with the configuration file copied over from the above instance, modified the unicast list of hosts to include the IP address of the above server instance. I started up the node instance with this configuration. I then checked on the cluster and saw the new instance being reported as an additional node. I then used curl to up the replication factor to 2 My questions are these : 1. How long does it take for the data to be synchronized /distributed so that the data is available to be queried properly ? 2. Is the process I follow above flawed ? (are there any issues with it and Can I recover by stopping the cluster and restarting them with proper configuration set) 3. Prior to addition of the node, I was able to query for documents older than 35 days (now-35d) but after the addition, this data is not available. a query for match\_all returns the right number of documents, except that the older documents do not seem to be query able . If the new node that was added goes away how is the data affected ? Thanks for the responses and assists.

1 - Depends on how much data you have. 2 - Yes, two replicas will mean one will never be assigned. This is because you have 2 nodes but 3 copies of the data. Set replica to just 1. 3 - That sounds very unusual. Have you tried to fetch one of these documents via id?

Hi Mark: Thanks, a few things were resolved. 1. I was running into heap memory issues on the new node, and the Cluster state went form being Yellow to Green almost immediately. 2. The problem with my query was not so much with lack of data or data not being replicated/copied over to the new node, But something see hokey with the date math. The query I was using before : { "query": { "bool": { "must": [ {"range": { "DOC\_DATE": { "from": "now-36d", "to": "now-35d" } }} ] } } } this would result in a number of documents. However after I added the new node: the same query would not return any docs. But when I changed it to { "query": { "bool": { "must": [ {"range": { "DOC\_DATE": { "from": "2014-11-14T00:00:00Z", "to": "2014-11-15T00:00:00Z" } }} ] } } } I got documents. Now the question is whats the problem with my prior query (if any).
