Can a Non-Global Zone NFS Mount a File System That Has Been Shared From It's Own Global Zone? (Doc ID 1528435.1)

Last updated on APRIL 26, 2023

Applies to:

Solaris Operating System - Version 10 10/09 U8 to 11.4 [Release 10.0 to 11.0]
Information in this document applies to any platform.

Goal

This document describes a current limitation of NFS: an NFS server and NFS clients cannot exists on the same Solaris system (instance) - unless the shared filesystem is ZFS and the OS version is Solaris 11.2 or later.   Per the Solaris 11.4 mount_nfs(8) man page:

An NFS server should not attempt to use NFS to mount the file systems it serves, unless they are provided by zfs(4FS).  For an alternative to NFS mounts of file systems from the same host, see the lofs(4FS) man page.

 In this case the customer configured the NFS server on the global zone and the file system in question is mounted in a non-global zone - using NFS - on the same server.

As a result of this, performance issues were observered when large files were transferred over NFS.
