I have been trying to find a solution to this here on this group and many Google searches. I set up ES with 5 shards per index, 0 replicas. I create a new index by day and hour and have loaded content. After loading 750M records, I end up with 1425 shards across 285 indices. Everything is working fine. Now I want to add a replica, so I use the curl command: curl -XPUT 'localhost:9200/\*/\_settings' -d '{ "index": { "number\_of\_replicas" : 1}}' Which also worked fine - I can query ES and see that each index is marked as having 1 replica. The shards however that would be the replica shards are marked as Unassigned. How do I go about forcing ES to actually replicate the indexes now into these replica shards?

My "is it plugged in" question: do you have more than one node in your cluster? Like, check localhost:9200/\_cluster/health and make sure. Beyond that, does the health api tell you that some are being assigned? Are there any logs about failure to assign?

How many nodes do you have? -- David Pilato | Technical Advocate | [Elasticsearch.com](http://Elasticsearch.com) @dadoonet | @elasticsearchfr Le 19 novembre 2013 at 23:04:49, Jerry Russell ([jerryrussell@gmail.com](mailto:jerryrussell@gmail.com)) a écrit: I have been trying to find a solution to this here on this group and many Google searches.

One node. Will replicas not be created if there is only one node? Thanks, Jerry -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

No. It does not really make sense to replicate data on the same node. -- David Pilato | Technical Advocate | [Elasticsearch.com](http://Elasticsearch.com) @dadoonet | @elasticsearchfr Le 19 novembre 2013 at 23:13:27, Jerry Russell ([jerryrussell@gmail.com](mailto:jerryrussell@gmail.com)) a écrit: One node.

ES will intentionally avoid replicating shards on the same node so the cluster is always redundant. You'd need to add another node for it to automatically replicate. -Andreas On Tuesday, November 19, 2013 2:13:24 PM UTC-8, Jerry Russell wrote: > One node.

I understand it doesn't make sense to replicate with one node. But I am seeing a weird problem with searching that I was hoping was related to not having a replica (always getting different number of search results for same search with static data). This problem I am running into did not occur on same data set when using two nodes with replicas, so I needed to confirm in the current environment if replicas were the real cause or not. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
