       nfsd - NFS daemon

       /usr/lib/nfs/nfsd [-a] [-c #_conn] [-l listen_backlog]
	    [-p protocol] [-t device] [nservers]

       nfsd is the daemon that handles client file system requests. Only users
       with {PRIV_SYS_NFS} and sufficient privileges to write to /var/run  can
       run this daemon.

       The  nfsd  daemon  is automatically invoked using share(1M) with the -a

       By default, nfsd starts over the TCP and UDP transports for versions  2
       and 3. By default, it starts over the TCP for version 4. You can change
       this with the -p option.

       A previously invoked nfsd daemon started with or without	 options  must
       be stopped before invoking another nfsd command.

       To  change  startup  parameters	for  nfsd,  use	 the  sharectl(1M) and
       sharemgr(1M) commands.

       The following options are supported:

		      Start a NFS daemon over all available connectionless and
		      connection-oriented  transports,	including UDP and TCP.
		      Equivalent of setting the NFSD_PROTOCOL parameter to ALL
		      in the nfs file.

       -c #_conn
		      This  sets  the maximum number of connections allowed to
		      the NFS server over connection-oriented  transports.  By
		      default, the number of connections is unlimited. Equiva‐
		      lent of the NFSD_MAX_CONNECTIONS parameter  in  the  nfs

		      Set  connection queue length for the NFS TCP over a con‐
		      nection-oriented transport.  The	default	 value	is  32
		      entries. Equivalent of the NFSD_LISTEN_BACKLOG parameter
		      in the nfs file.

       -p protocol
		      Start a NFS daemon over the specified protocol.  Equiva‐
		      lent of the NFSD_PROTOCOL parameter in the nfs file.

       -t device
		      Start  a	NFS  daemon for the transport specified by the
		      given device.  Equivalent of the	NFSD_DEVICE  parameter
		      in the nfs file.

       The following operands are supported:

		   This	 sets  the  maximum  number of concurrent NFS requests
		   that the server can handle. This concurrency is achieved by
		   up  to  nservers  threads  created as needed in the kernel.
		   nservers should be based  on	 the  load  expected  on  this
		   server.  16 is the usual number of nservers. If nservers is
		   not	specified,  the	 maximum  number  of  concurrent   NFS
		   requests  will default to 1. Equivalent of the NFSD_SERVERS
		   parameter in the nfs file.

       If the NFS_PORTMON variable is set in  /etc/system,  then  clients  are
       required	 to  use privileged ports (ports < IPPORT_RESERVED) to get NFS
       services. This variable is equal to zero by default. This variable  has
       been  moved  from  the  "nfs" module to the "nfssrv" module. To set the
       variable, edit the /etc/system file and add this entry:

       set nfssrv:nfs_portmon = 1

	    Daemon started successfully.

	    Daemon failed to start.

			       Client machine pointer to an  open-but-unlinked

			       Contains startup parameters for nfsd.

			       System configuration information file.

			       Directories used by the server to manage client
			       state information. These directories should not
			       be removed.

       ps(1),  svcs(1),	 mountd(1M),  share(1M),  sharectl(1M),	 sharemgr(1M),
       svcadm(1M), nfs(4), sharetab(4), system(4), attributes(5), smf(5)

       Manually starting and restarting nfsd is not recommended. If it is nec‐
       essary  to  do  so,  use	 svcadm	 to  enable or disable the nfs service
       (svc:/network/nfs/server). If it is disabled, it	 will  be  enabled  by
       share_nfs(1M),  unless  its  application/auto_enable property is set to
       false. See the , and svcadm(1M) for more information.

       The nfsd service is managed by the service management facility, smf(5),
       under the service identifier:


       Administrative actions on this service, such as enabling, disabling, or
       requesting restart, can be performed using  svcadm(1M).	The  service's
       status can be queried using the svcs(1) command.

       If nfsd is killed with SIGTERM, it will not be restarted by the service
       management facility. Instead, nfsd can be restarted by  other  signals,
       such as SIGINT.
