.SH DESCRIPTION
The
.B rpc.statd
server implements the NSM (Network Status Monitor) RPC protocol.
-This service is somewhat misnomed, since it doesn't actually provide
+This service is somewhat misnamed, since it doesn't actually provide
active monitoring as one might suspect; instead, NSM implements a
reboot notification service. It is used by the NFS file locking service,
.BR rpc.lockd ,
.B -F
parameter.
.TP
+.BI "\-n," "" " \-\-name " name
+specify a name for
+.B rpc.statd
+to use as the local hostname. By default,
+.BR rpc.statd
+will call
+.BR gethostname (2)
+to get the local hostname. Specifying
+a local hostname may be useful for machines with more than one
+interfaces.
+.TP
+.BI "\-o," "" " \-\-outgoing\-port " port
+specify a port for
+.B rpc.statd
+to send outgoing status requests from. By default,
+.BR rpc.statd
+will ask
+.BR portmap (8)
+to assign it a port number. As of this writing, there is not
+a standard port number that
+.BR portmap
+always or usually assigns. Specifying
+a port may be useful when implementing a firewall.
+.TP
+.BI "\-p," "" " \-\-port " port
+specify a port for
+.B rpc.statd
+to listen on. By default,
+.BR rpc.statd
+will ask
+.BR portmap (8)
+to assign it a port number. As of this writing, there is not
+a standard port number that
+.BR portmap
+always or usually assigns. Specifying
+a port may be useful when implementing a firewall.
+.TP
+.BI "\-P," "" " \-\-state\-directory\-path " directory
+specify a directory in which to place statd state information.
+If this option is not specified the default of
+.BR /var/lib/nfs
+is used.
+.TP
+.B -N
+Causes statd to run in the notify-only mode. When started in this mode, the
+statd program will check its state directory, send notifications to any
+monitored nodes, and exit once the notifications have been sent. This mode is
+used to enable Highly Available NFS implementations (i.e. HA-NFS).
+.TP
+.BI "\-H, " "" " \-\-ha-callout " prog
+Specify a high availability callout program, which will receive callouts
+for all client monitor and unmonitor requests. This allows
+.B rpc.statd
+to be used in a High Availability NFS (HA-NFS) environment. The
+program will be run with 3 arguments: The first is either
+.B add-client
+or
+.B del-client
+depending on the reason for the callout.
+The second will be the name of the client.
+The third will be the name of the server as known to the client.

Causes
.B rpc.statd
You have to use the daemon name
.B statd
-for the daemon name (even if the binary has a different name). For the
-client names you can only use the keyword ALL or IP addresses (NOT
-host or domain names).
+for the daemon name (even if the binary has a different name).
For further information please have a look at the
-.BR tcpd (8),
-.BR hosts_allow (5)
+.BR tcpd (8)
and
.BR hosts_access (5)
manual pages.
+.SH SIGNALS
+.BR SIGUSR1
+causes
+.B rpc.statd
+to re-read the notify list from disk
+and send notifications to clients. This can be used in High Availability NFS
+(HA-NFS) environments to notify clients to reacquire file locks upon takeover
+of an NFS export from another server.
