       nfs.conf - general configuration for NFS daemons and tools




       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
       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

       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-


       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-

              Recognized values: pipefs-directory.

              See blkmapd(8), rpc.idmapd(8), and rpc.gssd(8) for details.

              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.

              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.

              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.

              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.

              Recognized values: principal, verbosity, rpc-verbosity, idmap-verbosity.

              See rpc.svcgssd(8) for details.

              Only debug= is recognized.

              Recognized values: nfs, nfsv4, default.

              See nfsrahead(5) for deatils.


                 Default NFS client configuration file

                 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
