Introducing the /etc/exports file

/etc/exports controls client access to directories

The /etc/exports file controls how NFS clients access filer directories. You add entries to the /etc/exports file for all the directories you want to export.

Format for /etc/exports entries

The format of the entries in the /etc/exports file is as follows:

filer_directory_path export_specification

Filer directory path format

The filer directory path specifies which directory is made available to clients. The format is as follows:

/vol/volume_name/directory

Examples

The following lines show examples of filer directory paths:

/vol/vol0/home

/vol/users/local/jarnold

Export specification determines access privileges

The export specification specifies the privileges that clients have to mount and access the filer directory path. The format is as follows:

-root=list,-access=list,-ro=list,-rw=list

One keyword is required

The keywords -root, -access, -ro, and -rw are all optional; however, you must include at least one keyword in an export entry.

What the list variable represents

The list variable represents a list that includes one or more

• host names
• netgroup names
• subnets

You can combine elements in an entry

You can combine host names, netgroup names, and subnets in an entry, as shown in the following example:

-root=adminhost:administrators,-rw=blender:pcusers:123.45.67.0/24

Example 1: exporting default filer volume to administration host

The following line exports the root directory of the default filer volume to the administration host with root privileges. The administration host can mount the directory, change permissions and ownerships, and create and delete directories and files.

/vol/vol0 -root=adminhost

Example 2: exporting home directory to administration host and clients

The following line exports the home directory from the default filer volume to the administration host and two clients. The administration host has root privileges and can mount the directory, change permissions and ownerships, and create and delete directories and files. The clients can mount the directory and create and delete directories.

/vol/vol0/home -root=adminhost,-rw=blender:mixer
