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 JANUARY 18, 2022

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.


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 mount_nfs(1M) man page:

An NFS server should not attempt to mount its own file systems. An NFS server can mount its own file systems only if it is provided by ZFS. See lofs (7FS) .

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

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