I had to delete all my data from my elasticsearch/data/nodes/\* folder because index "cust\_name\_abc" had a transaction log read error. Which stopped my entire ELK stack.

In the future how do I find the matching elasticsearch/data/nodes/xxx folder for "cust\_name\_abc"

The data folder had folder names with random number & letters.

Thanks

Removing files from the Elasticsearch **path.data** directory is quite dangerous and not a recommended way of cleaning up bad data, the only times I've done so is when I've done a clean install on an old Elasticsearch node - then I remove the entire data directory to create a fresh one.

If you need to get rid of a faulty index, just use the [Delete Index](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-index.html) mechanism - it allows you to delete one or several indices via a curl command (or from Kibana). For instance

`curl -X DELETE "localhost:9200/facebook-*"`

will delete all indices with names starting with "facebook-". This is quick and much safer than removing files from the data directory.
