ES ver. 7.4

I want to block all write actions (create/update/delete) to my index. I need it to copy docs to another index using `reindex` action and keep 100% consistency between indicies.

So what I do is:

```auto
curl -X PUT \
  https://elasticsearch/foo-bar/_settings \
  -H 'Content-Type: application/json' \
  -d '{
	"index": {
		"blocks": {
			"write": true
		}
	}
}'

```

Then I verify it:

```auto
curl -X GET 'https://elasticsearch/foo-bar/_settings?include_defaults=true'

```

And the response is correct:

```auto
settings.index.blocks.write = true

```

But after some time about 1 min, this value changes automatically to `false`.

There is nothing in documentation about anything that manages this value: [https://www.elastic.co/guide/en/elasticsearch/reference/master/index-modules-blocks.html](https://www.elastic.co/guide/en/elasticsearch/reference/master/index-modules-blocks.html)

Does anyone know what happens, what change that value?

On top of my head no component should do that.

You can increase some logging to monitor when this is set by running

```auto
PUT /_cluster/settings
{
  "transient": {
    "logger.org.elasticsearch.cluster.service.MasterService": "debug"
  }
}

```

And check the master node logs. Don't forget to set this to `INFO` again...

Do you have any component like curator running?
