Hi

Welcome!

You can't have more than 1000 shards per node.

Here I think you have only one node.

So either you start 2 more nodes, or you remove some of the existing indices.

What is the output of:

```auto
GET /
GET /_cat/nodes?v
GET /_cat/health?v
GET /_cat/indices?v

```

If some outputs are too big, please share them on [gist.github.com](http://gist.github.com) and link them here.
