Keystore.tmp issue

Hi community!

I am running into an issue when deploying elastic search with security / alerting plugin on Openshift. I believe my configuration is setup correctly (config.yml / elasticsearch.yml) and mounted.

The error I am receiving

Exception in thread "main" org.elasticsearch.bootstrap.BootstrapException: java.nio.file.FileSystemException: /usr/share/elasticsearch/config/elasticsearch.keystore.tmp: Read-only file system

I spent the better half of my day trying to figure this out. Any help would be greatly appreciated .
