Hi,  
When the disk usage reaches the threshold, will elasticsearch stop processing the incoming indexing requests?

Running ES 2.3.2 and its a single node ES cluster?

Logs?  
[2017-06-01 13:24:53,368][INFO][cluster.routing.allocation.decider] [Kismet] low disk watermark [85%] exceeded on [pd1E5-TmT6mhoTkkRay0\_g][Kismet][C:\tt\tt\elasticsearch-2.3.2\data\WF\_PROD1\nodes\0] free: 35.4gb[14.7%], replicas will not be assigned to this node

Please format your code using `</>` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will make your post more readable.

Or use markdown style like:

````
```
CODE
```

````

It will continue to index data but will refuse to allocate replicas on that node.
