Hi!

My elastic node is old and has been upgraded over time from v5.x to v6.2.4 currently. I've had index with pattern logstash-\* in the past but right now I've no index with name logstash.

I wanted to try out the geo features and chose to use [logs sample data](https://www.elastic.co/guide/en/kibana/current/tutorial-load-dataset.html) and followed the page to load the data. When I try to do the mappings for `PUT /logstash-2015.05.18`, I get the following error. Changing the mappings index to `PUT /logs-2015.05.18` works fine.

How do I find any remnants of old index `logstash-*` and clean it up?
