Hi There,

I am having an issue while trying to perform PUT request from [ElasticSearch.Net](http://ElasticSearch.Net). First run successsfully inserts the document record, however when i update the data for another document and runs again, it just throws an error.

Here is the error the i get,

> {  
> "error": {  
> "root\_cause": [{  
> "type": "cluster\_block\_exception",  
> "reason": "blocked by: [FORBIDDEN / 12 / index read - only / allow delete(api)];  
> "}],"  
> type ":"  
> cluster\_block\_ex  
> ception ","  
> reason ":"  
> blocked by: [FORBIDDEN / 12 / index read - only / allow delete(api)];  
> "},"  
> status ":403  
> }

I again have to perform the below PUT Operation to make it work,

> ```
> PUT employees/_settings
> {
> "index": {
> "blocks": {
> "read_only_allow_delete": "false"
> }
> }
> }
> 
> ```

My Sample Test C# Snippet looks like this,

It would be great if someone could help to overcome this issue.

Thanks,  
Rammohan B.

That can be a sign that you are running out of disk space and have exceeded the [flood stage watermark](https://www.elastic.co/guide/en/elasticsearch/reference/6.4/disk-allocator.html). Have a look at how large percentage of your disk space that is still free.
