Lesson 1: Exporting a Mounted File System to UNIX
This lesson covers the following topics:
• NFS Client mounts
• NFS user authentication

NFS Export
• Network File System (NFS) protocol
 Client or server distributed file service
 Provides file sharing in network environments
• VNX Data Mover or VDM is configured as an NFS server
 Provides file system access for clients of NFS versions 2, 3 and 4

Access Control
• Client access to NFS Exports defined by
 Hostname
 Netgroup
 Subnet
 IP address
• Authentication methods
 Unix Security or AUTH_SYS security
 Secure NFS
 Authentication Daemon
• All versions support UNIX security / PC authentication daemon
 Only versions 3 and 4 support Secure NFS by using either
UNIX/Linux or Windows Kerberos KDC

Mounting a File System to a Mountpoint
• Storage > Storage Configuration
 File Systems tab, right-click file system > Mounts > Create Mount
 Mounts tab > Create
• By default a file system is mounted when it is created

Mounting the File System from Clients (NFS)
• NFS mount from client
 Manual
 Automatic (automounter)
• Typical Procedure
 Create or use an empty local directory as a mount point for the
exported file system
 NFS mount the local directory to the exported File System
 mount <NFS server IP address or FQDN>:/<exported fs>
/<mount point>
 Example
 # mount 192.168.1.106:/fs1 /studentX
• View the file systems mounted on the client
 mount
 df –h

Export a File System Directory
• Root of file system contains .etc and lost&found directories
• Network users are unaware of the purpose of these directories
• Best practice
 Mount the file system at subdirectory level, export at that level and hide
.etc and lost&found
[[email protected] fs1]# ls –al
drwxr-xr-x 5 root root 1024
drwxr-xr-x 28 root root 4096
dr-xr-xr-x 2 root bin
