export and unexport directories to NFS clients
/usr/sbin/exportfs [-aiuv] [-o options] [pathname]
The exportfs command makes a local directory or filename
available for mounting over the network by NFS® clients.
All. Export all pathnames listed in /etc/dfs/dfstab, or if
-u is also specified, unexport all of the currently exported
Ignore the options in /etc/dfs/dfstab. Normally, exportfs
will consult /etc/dfs/dfstab for the options associated with
the exported pathname.
Unexport the indicated pathname. A pathname is
required if -u is not used in conjunction with -a.
Verbose. Print each directory or filename as it is exported or unexported.
Specify a comma-separated list of optional characteristics for the
pathname being exported. options can be selected from among:
Export the pathname read-only. If not specified, the pathname
is exported read-write.
rw= hostname[: hostname] ...
Export the pathname read-mostly. Read-mostly means exported read-only
to most machines, but read-write to those specified. If not specified,
the pathname is exported read-write to all.
If a request comes from an unknown user, use UID as the effective
root users (UID) are always considered ``unknown'' by the
NFS server, unless they are included in the root option below.
The default value for this option is -2. Setting the value of
anon to -1 disables anonymous access.
root= hostname[: hostname] ...
Give root access only to the root users from a specified hostname.
The default is for no hosts to be granted root access.
access= client[: client] ...
Give mount access to each client listed.
You cannot export a directory that is either a parent- or a sub-directory
of one that is currently exported and within the same filesystem.
It would be invalid, for example, to export both /var and
/var/spool if both directories resided in the same disk
static export information
current state of exported pathnames
exportfs uses information contained in the
/etc/dfs/dfstab file to export pathname (which must
be specified as a full pathname). The user with appropriate administrative
privileges can run exportfs at any time to alter the list or
characteristics of exported directories and filenames. Directories and
files that are currently exported are listed in the file
With no options or arguments, exportfs prints out the list of
directories and filenames currently exported.
