Path.repo filesystem in linux

Elastic Stack Elasticsearch
1

We have added the filesystem to path.repo but while creating the repository for snapshot and restore we are getting the below error

"This might indicate that the store is not shared between this node and the master node or that permissions on the store don't allow reading files written by the master node"

Whether we need to mount that filesystem? If yes, how?

The same repo needs to be shared on all nodes.

So yes you need to "mount" this dir on all systems.

How?

I have no idea because it's not related to elasticsearch but a Linux question.
