.SH NAME
statd \- network status monitor
.SH SYNOPSIS
.LP
.nf
\fB/usr/lib/nfs/statd\fR 
.fi

.SH DESCRIPTION
.sp
.LP
\fBstatd\fR is an intermediate version of the status monitor. It interacts with
\fBlockd\fR(1M) to provide the crash and recovery functions for the locking
services on NFS. \fBstatd\fR keeps track of the clients with processes which
hold locks on a server. When the server reboots after a crash, \fBstatd\fR
sends a message to the \fBstatd\fR on each client indicating that the server
has rebooted. The client \fBstatd\fR processes then inform the \fBlockd\fR on
the client that the server has rebooted. The client \fBlockd\fR then attempts
to reclaim the lock(s) from the server.
.sp
.LP
\fBstatd\fR on the client host also informs the \fBstatd\fR on the server(s)
holding locks for the client when the client has rebooted. In this case, the
\fBstatd\fR on the server informs its \fBlockd\fR that all locks held by the
rebooting client should be released, allowing other processes to lock those
files.
.sp
.LP
\fBlockd\fR is started by \fBautomountd\fR(1M), \fBmount_nfs\fR(1M), and
\fBshare\fR(1M) if NFS automounts are needed.

.SH NOTES
.sp
.LP
The crash of a server is only detected upon its recovery.
.sp
.LP
The \fBstatd\fR service is managed by the service management facility,
\fBsmf\fR(5), under the service identifier:
.sp
.in +2
.nf
svc:/network/nfs/status
.fi
.in -2
.sp

.sp
.LP
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using \fBsvcadm\fR(1M). The service's
status can be queried using the \fBsvcs\fR(1) command.
.sp
.LP
If it is disabled, it will be enabled by \fBmount_nfs\fR(1M),
\fBshare_nfs\fR(1M), and \fBautomountd\fR(1M) unless  its
\fBapplication/auto_enable\fR property is set to \fBfalse\fR.
