Does the Elasticsearch user have the read and write permissions on the directory? Is it a shared drive available to all nodes in the cluster? ---

`/opt/nfsstorage` is not accessible on node `tmz-mc2`. Check that you mount it. ---

Yes. I believe it's not related to elasticsearch but to your shared FS config. You need to fix that to make sure that your user running elasticsearch can read and write a file from both nodes. May be a mount issue? ---

What are your mount options? Make sure that the elasticsearch user has same uid / gid on both tmz-mc1 and tmz-mc2. ---

You can use the `usermod` and `groupmod` commands to change the UID and GID. Make sure they are the same on the server and all client machines for the given user name. e.g. `usermod -u 5555 my_user_name` and `groupmod -g 6666 my_group_name` You will have to make sure that any directories that you created outside of the user's home folder have the permissions changed to include the new UID and GID. A google search for "changing the uid and gid mappings on linux" yields several pages and examples. Check out the man pages for each command as well. ---
