Unable to create snapshots

Elastic Stack Elasticsearch
1

My cluster is on elasticsearch 2.3, with 3 data nodes and 2 none data nodes, on the data nodes, I setup the NFS mount and added the data.repo to the elasticsearch.yml file. when I issue
PUT /_snapshot/my_backup
{
"type": "fs",
"settings": {
"location": "/mount/esbackup/"
}
}
I got following in return. I am wonder whether I should mount the NFS folder on the nodes that have no data, or is there anything else I need to check.
Thanks for your help.

Did you mean path.repo?

yes. Sorry

You need to add this on all nodes and restart your nodes.

I added the mounting point on every node, checked the file path is accessible, added path:repo to elasticsearch.yml, also restart elasticsearch on every node with no luck. looking at the /var/log/elasticsearch/elasticsearch.log, it says the same error.

double check again there was a mistype in my mounting point, so repo is configured ok after the typo correction.
