Elasticsearch Failure node lock error

Elastic Stack Elasticsearch
1

Hi,

I've changed the data path to a shared folder under /mnt/share/elasticsearch. And moved the elasticsearch folder there. When I try to start elasticsearch I get the following error.

Caused by: java.nio.file.AccessDeniedException: /mnt/share/elasticsearch/nodes/0/node.lock**

The permissions on the folder are as follows.

root@laboelk01:/var/lock/subsys# ls -l /mnt/share/elasticsearch/                                                                                                  
total 0
drwxr-xr-x 2 root root 0 May 17 15:37 nodes

I think it has something to do with node lock but I've been unsuccessful in resolving the issue.
If anybody could help me out it I would greatly appreciate it.

It looks like your data path is owned by root and no other users can modify it, whereas Elasticsearch is not (and should not be) running as root. You should change the owner of the data path to the user of the Elasticsearch process.
