Имя (Name)
nfs.conf - general configuration for NFS daemons and tools
Синопсис (Synopsis)
/etc/nfs.conf
Описание (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, vers2, 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.
Файлы (Files)
