Hi , I started a index with 5 shards and 1 replica on our integration(INT) environment on a single machine.(This is to make sure i can scale the index , if needed ,in future) Unfortunately when i plugged my dev box to the INT environment network , the ES instance running on my box automatically hooked up (What a bitch [?] ) with the master ES instance in the INT environment ☹ (As it is in multi-cast discovory more ). Due to this half the documents i have is in my dev box and rest in INT box. How can i decommission the node running on my dev box. That is i need to transfer the documents to the INT box and shutdown the DEV instance for the good. Thanks Vineeth ---

I suggest changing your cluster name for each env : For dev instances, use : ES-DEV-USERNAME (in case of many developpers) For INT instances, use : ES-INT For production, use : ES-PROD So even, nodes can see each other on the network, they won't try to work for another cluster.

Just shut down the node on your DEV box, and the INT server's replica shard will be promoted to primary. clint ---

When i shut down the dev box , things were working fine at master but it lost some documents. When i brought back dev instance all these documents came back. I dont want to loose any document in the process.

@David - changing cluster name will help in future. But can i get a fix to this scenario.

Are you sure that your index is set to {number\_of\_replicas: 1} then? If you have 1 replica, and 2 nodes, then all your docs should be on both nodes. clint ---

Nope its 0 replica and 5 shards. Sorry for the wrong details b4.

thanks dude. Looks like a workable idea.
