exportfs - export and unexport directories and files
exportfs [ -aiuv ] [ -o options ] [ pathname ]
If no pathname is specified, exportfs lists all currently
exported directories and filenames. If pathname is specified,
exportfs makes the directory or file specified by
pathname available for mounting over the network by NFS
clients.
-a Takes the list of pathnames to be exported or unexported
from /etc/exports. (This has the effect of
ignoring pathname if the command included pathname.)
- -i
- Ignores the options in /etc/exports. Normally,
exportfs uses the options associated with the pathname
specified in /etc/exports, if available.
- -u
- Unexports the specified pathname. However, if -a is
also specified, unexports the pathnames listed in
/etc/exports and ignores pathname.
- -v
- Prints each pathname as it is exported or unexported.
- -o options
-
Specifies a comma-separated list of options for the
pathname being exported. options can be any of the
following:
access=hostname[:hostname]...
Restricts access to the hosts listed. A netgroup
defined in /etc/netgroup can be specified in place
of a hostname for this option.
anon=uid
If a request comes from user ID of 0 (root user ID
on the client), use uid as the effective user ID
unless the client host is included in the root
option below. The default value is 65534. Setting
the value of "anon" to 65535 disables all
root access. A value of 0 grants root access to
all clients.
ro Exports the pathname read-only. If not specified,
pathname is exported read/write.
rw=hostname[:hostname]...
Exports the pathname read-only to all hosts not
specified in the list and read-write to the hosts
in the list. Netgroup names are not allowed in
the list.
root=hostname[:hostname]...
Gives root access only to the specified hosts.
The default is for no hosts to be granted root
access. Netgroup names are not allowed in the
list.
- /etc/exports
- directories and files exported to
NFS clients
- /etc/hosts
- host name data base
- /etc/netgroup
- network groups data base
na_exports(5), na_hosts(5), na_netgroup(5)
Data ONTAP supports a maximum of 100 hostnames in each rw=
and root= option. There is no limit on the number of hostnames
in an individual access= list, but the total size of
/etc/exports is limited to about 64 KB.
