NAME

       nfsd - NFS daemon

SYNOPSIS

       /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 option.

       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.

       Administrators wanting to change startup parameters for nfsd should, as root, make changes in the /etc/default/nfs file. See nfs(4).

       The following options are supported:

       -a              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. Equivalent of the NFSD_MAX_CONNECTIONS parameter in the nfs file.

       -l              Set  connection queue length for the NFS TCP over a connection-oriented transport. The default value is 32 entries. Equiva-
                       lent of the NFSD_LISTEN_BACKLOG parameter in the nfs file.

       -p protocol     Start a NFS daemon over the specified protocol. Equivalent 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:

       nservers        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.

USAGE

       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

       0        Daemon started successfully.

       1        Daemon failed to start.

       .nfsXXX                         Client machine pointer to an open-but-unlinked file.

       /etc/default/nfs                Contains startup parameters for nfsd.

       /etc/system                     System configuration information file.

       /var/nfs/v4_state               Directories used by the server to manage client state information. These directories should not be removed.
       /var/nfs/v4_oldstate

       Manually starting and restarting nfsd is not recommended. If it is necessary 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:

       svc:/network/nfs/server

       Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed  using  svcadm(1M).  The  ser-
       vice'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 sig-
       nals, such as SIGINT.
