Hello  
I want to run elasticsearch shows me the following error  
[error][o.e.b.Elasticsearch] [nodename] fatal exception while booting Elasticsearch java.lang.illegalStateExcption: failed to obtain node locks,tride[/media/............/elasticsearch]; maybe these locations are not writable or multiple nodes were started on the same data path?

For your information, the folder in which the cursors are located in a storage disk other than the disk in which elasticsearch is located

A couple things to check:

- Make sure the storage disk is properly mounted and accessible, and the user running Elasticsearch has access to that disk
- Make sure there is only one instance running (`ps aux | grep elasticsearch`) and stop the extra instances if there are multiple indices running
- Make sure your data directory is correctly configured in `elasticsearch.yml`
- Check the Elasticsearch logs to see if there is additional information
