 Currently, we recommend that you use NFS version 3.0 for running WebLogic Server on OCI Container Engine for Kubernetes. During certification, we found that when using NFS 4.0, the servers in the WebLogic domain went into a failed state intermittently. Because multiple threads use NFS (default store, diagnostics store, Node Manager, logging, and `domain_home`), there are issues when accessing the file store. These issues are removed by changing the NFS to version 3.0.

 The `HOST_PATH` directory permissions can be made more secure by using a Kubernetes annotation on the
 persistent volume that provides the group identifier (GID) which will be added to pods using the persistent volume.
