Elastic 7.11.1

Today, two of my elastic hosts (where there is 0 replicas), somehow created this index with number\_of\_replicas=1

`yellow open ilm-history-3-000004`

That is why it is in yellow state.

When I look index templates, then I see this:

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/c/b/cb40e5417ba8cd414b922e1c2c0a0baa791cd24d.png)

This **ilm-history** template has the following settings:

```
{
  "index": {
    "lifecycle": {
      "name": "ilm-history-ilm-policy"
    },
    "number_of_shards": "1",
    "auto_expand_replicas": "0-1",
    "number_of_replicas": "0"
  }
}

```

Here it says that **"number\_of\_replicas": "0"**  
But look at the **"Index patterns"** from the picture above.

Template has: "ilm-history-5\*"  
But the index which was created: "ilm-history-3-000004"

So why ilm-history index was created with different name than its template..?  
If there is no template for certain index, is the default value for number\_of\_replicas = 1 ? (if so, can I change this default?)

I believe auto\_expand\_replicas takes precedence here resulting in 1 replica.

But look at the index pattern.

"ilm-history-5\*"  
vs  
"ilm-history-3-000004"

There is no way these could match.

Yes.

Effectively yes, that's what index templates are for.

But the problem.

ilm-history \<-- this is not user created index, this is internally managed index/template.

Am I supposed to create index template for internally managed indexes..?  
(I don't think so)

Ah I see. I don't think a 7.11.1 cluster should create an index matching `ilm-history-3-*`, do you have a mix of different versions in your cluster?

Nop.  
As I said. I have single host cluster with 7.11.1 version.

I don’t have any template for “ilm-history-5\*” also.  
For some reason template is for “ilm-history-3\*”  
And index was created starting with “ilm-history-5..”

Strange.

That's precisely the opposite of what you said in your original post: the index is called `ilm-history-3-000004` but the template in the screenshot matches `ilm-history-5*`.

Yeah my bad.  
That previous post was wrong.

This is the correct one:

I don’t have any template for “ilm-history-3\*” also.  
For some reason template is for “ilm-history-5\*”  
And index was created starting with “ilm-history-3..”

I have checked all my 7.11.1 clusters.  
All of these have the same behaviour - at midnight clusters all went to "yellow" state due to this "ilm-history-3" index.

E: "yellow" state followed for all the clusters where I had single host in cluster. But the issue still stands for multi node clusters also, since it is not using its designated index template.

I think you could report this as a bug on Github, it certainly sounds like Elasticsearch isn't doing the right thing here.

Ok, I see this beahviour with 7.11.2 also.  
I will create an issue.
