We have 2 nodes, but there is no common way.
When to take a snapshot through curator_cli:
2019-04-12 14:53:04,899 CRITICAL Failed to complete action: snapshot. <class 'curator.exceptions.ActionError'>: Failed to verify all nodes have repository access: --- Got a 500 response from Elasticsearch. Error message: repository_verification_exception
Can you create a repository for each node independently?
There is no access to folders from one node to another.
