Cannot start ES 6.4

Elastic Stack Elasticsearch
1

I am working on a new Elastic stack cluster and I am unable to start Elastic. I am assuming it is a filesystem/permissions issue, but I cant pin it down. I have a 1TB Samba share that is mounted to /home/elastic/esstorage and in the elasticsearch.yml i have "path.data: /home/elastic/esstorage". there was a permissions issue, but i corrected it and cleared out the files that were created under the wrong credentials, but now I am running into this error when i try to start elastic

I assume that the "sun.nio.fs.UnixFileSystem.getPath(UnixFileSystem.java:273)" means it is a filesystem error of some kind, but for the life of me i can't figure out what it is.

I appreciate any help.

I'd open an issue as getting a NPE is never a good thing.

However it's absolutely not recommended to use a network drive to store elasticsearch data. You should not do that IMHO.

Thank you, I Went over it with Management and we're moving away from the CIFS share.
