Elastic Stack Elasticsearch

Hi! I want to use es as my resources server.
To support my users, I was planning on raising 2 servers with one instance
on each server.
Configuring the two nodes as a cluster with 8 shards for future scaling and
2 replicas for better performance .
Also i want to set zen discovery to use unicast so that the two nodes will
work synchronically.

My question is, will this configuration work for me?
How do i make sure that it works? Just by calling the indexes and check its
data?

If you're looking to add another node in soon then keep that replica
number, otherwise 1 replica will be enough (one per node). You can change
the replica number at a later date if you wish.

That config will work for what you want. Install a plugin like
kopf/elastichq/bigdesk and you will easily see what the status of the
cluster is, some of them also allow you to view documents in an index.

In addition to this, for production, I would recommend to start with 3 nodes. It will help you to reduce split brain issues risk.
Set minimum master node to 2.

My 2 cents.

Set minimum master node to 2.

As David points out, you’ll really want to have minimum master nodes of 2, even though the cluster only has two nodes: In a two-node cluster, you need to have both nodes to have a majority. 1 of 2 is not a majority, but a split brain.

Thus the third node.

Note, however, that the third node can be a cheap node without any data. (I.e. node.data is false) Then it’ll just participate to form a majority if a network partition happens.

I’ve written an article that has a bit more details about this here: Elasticsearch: The Official Distributed Search & Analytics Engine | Elastic

Hope this helps! :slight_smile:
