NAME
nfs.conf - general configuration for NFS daemons and tools
SYNOPSIS
/etc/nfs.conf
DESCRIPTION
This file contains site-specific configuration for various NFS daemons
and other processes. Most configuration can also be passed to
processes via command line arguments, but it can be more convenient to
have a central file. In particular, this encourages consistent
configuration across different processes.
When command line options are provided, they override values set in
this file. When this file does not specify a particular parameter,
and no command line option is provided, each tool provides its own
default values.
The file format supports multiple sections, each of which can contain
multiple value assignments. A section is introduced by a line
containing the section name enclosed in square brackets, so
-
[global]
would introduce a section called
global.
A value assignment is a single line that has the name of the value, an
equals sign, and a setting for the value, so
-
threads = 4
would set the value named
threads
in the current section to
4.
Leading and trailing spaces and tab
are ignored, as are spaces and tabs surrounding the equals sign.
Single and double quotes surrounding the assigned value are also
removed. If the resulting string is empty, the whole assignment
is ignored.
Any line starting with
``#''
or
``;''
is ignored, as is any blank line.
If the assigned value started with a
``$''
then the remainder is treated as a name and looked for in the section
[environment]
or in the processes environment (see
environ(7)).
The value found is used for this value.
The value name
include
is special. If a section contains
-
include = /some/file/name
then the named file will be read, and any value assignments found
there-in will be added to the current section. If the file contains
section headers, then new sections will be created just as if the
included file appeared in place of the
include
line.
If the file name starts with a hyphen then that is stripped off
before the file is opened, and if file doesn't exist no warning is
given. Normally a non-existent include file generates a warning.
Lookup of section and value names is case-insensitive.
Where a Boolean value is expected, any of
true,
t,
yes,
y,
on, or
1
can be used for "true", while
false,
f,
no,
n,
off, or
0
can be used for "false". Comparisons are case-insensitive.
SECTIONS
The following sections are known to various programs, and can contain
the given named values. Most sections can also contain a
debug
value, which can be one or more from the list
general,
call,
auth,
parse,
all.
When a list is given, the members should be comma-separated.
- general
-
Recognized values:
pipefs-directory.
See
blkmapd(8),
rpc.idmapd(8),
and
rpc.gssd(8)
for details.
- exports
-
Recognized values:
rootdir.
Setting
rootdir
to a valid path causes the nfs server to act as if the
supplied path is being prefixed to all the exported entries. For
instance, if
rootdir=/my/root,
and there is an entry in /etc/exports for
/filesystem,
then the client will be able to mount the path as
/filesystem,
but on the server, this will resolve to the path
/my/root/filesystem.
- exportd
-
Recognized values:
threads,
cache-use-upaddr,
ttl,
state-directory-path
See
exportd(8)
for details.
Note that setting
"debug = auth"
for
exportd
is equivalent to providing the
--log-auth
option.
- nfsdcltrack
-
Recognized values:
storagedir.
The
nfsdcltrack
program is run directly by the Linux kernel and there is no
opportunity to provide command line arguments, so the configuration
file is the only way to configure this program. See
nfsdcltrack(8)
for details.
- nfsd
-
Recognized values:
threads,
host,
port,
grace-time,
lease-time,
udp,
tcp,
vers3,
vers4,
vers4.0,
vers4.1,
vers4.2,
rdma,
Version and protocol values are Boolean values as described above,
and are also used by
rpc.mountd.
Threads and the two times are integers.
port
and
rdma
are service names or numbers. See
rpc.nfsd(8)
for details.
- mountd
-
Recognized values:
manage-gids,
descriptors,
port,
threads,
reverse-lookup,
cache-use-upaddr,
ttl,
state-directory-path,
ha-callout.
These, together with the protocol and version values in the
[nfsd]
section, are used to configure mountd. See
rpc.mountd(8)
for details.
Note that setting
"debug = auth"
for
mountd
is equivalent to providing the
--log-auth
option.
The
state-directory-path
value in the
[mountd]
section is also used by
exportfs(8).
- statd
-
Recognized values:
port,
outgoing-port,
name,
state-directory-path,
ha-callout.
See
rpc.statd(8)
for details.
- lockd
-
Recognized values:
port
and
udp-port.
See
rpc.statd(8)
for details.
- sm-notify
-
Recognized values:
retry-time,
outgoing-port, and
outgoing-addr.
See
sm-notify(8)
for details.
- gssd
-
Recognized values:
verbosity,
rpc-verbosity,
use-memcache,
use-machine-creds,
use-gss-proxy,
avoid-dns,
limit-to-legacy-enctypes,
context-timeout,
rpc-timeout,
keytab-file,
cred-cache-directory,
preferred-realm,
set-home.
See
rpc.gssd(8)
for details.
- svcgssd
-
Recognized values:
principal.
See
rpc.svcgssd(8)
for details.
- exportfs
-
Only
debug=
is recognized.
- nfsrahead
-
Recognized values:
nfs,
nfsv4,
default.
See
nfsrahead(5)
for deatils.
FILES
- /etc/nfs.conf
-
Default NFS client configuration file
- /etc/nfs.conf.d
-
When this directory exists and files ending
with ".conf" exist, those files will be
used to set configuration variables. These
files will override variables set in /etc/nfs.conf
