Can a non-global zone NFS-mount a file system that has been shared from its own global zone?
(Doc ID 1528435.1)
Last updated on FEBRUARY 03, 2019
Applies to:
Solaris Operating System - Version 10 10/09 U8 to 11.3 [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 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.
