Error restarting service after change data path

I made a clean install of elasticsearch and changed the data.path in the yml file like this:

path.data: /media/ssd/elasticsearch_data/

but I'm getting an error every time I restart the service:

Sep 16 11:46:03 hel systemd[1]: Starting Elasticsearch...

The log says:

Is there any permission requirement for this folder?

Yeah, the elasticsearch user needs read and write.

I fixed it by giving the right permissions to the mount point. My fault. :expressionless:
But is fixed now ! :smile:
