It interacts with \fBlockd\fR(8) 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(8), \fBmount_nfs\fR(8), and \fBshare\fR(8) if NFS automounts are needed. .SS "SMF Management" .sp .LP The \fBstatd\fR service is managed by the service management facility, \fBsmf\fR(7), 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(8). The service's status can be queried using the \fBsvcs\fR(1) command. .sp .LP The \fBsharectl\fR(8) command is used to manipulate the startup SMF parameters for \fBstatd\fR. Currently supported parameter is as follows: .sp .ne 2 .mk .na \fB\fBstatd_servers\fR=\fInum\fR\fR .ad .br .sp .6 .RS 4n Maximum number of concurrent \fBstatd\fR requests. The default is \fB1024\fR. .RE .SH FILES .sp .ne 2 .mk .na \fB\fB/var/statmon/sm\fR\fR .ad .br .sp .6 .RS 4n lists hosts and network addresses to be contacted after a reboot .RE .sp .ne 2 .mk .na \fB\fB/var/statmon/sm.bak\fR\fR .ad .br .sp .6 .RS 4n lists hosts and network addresses that could not be contacted after last reboot .RE .sp .ne 2 .mk .na \fB\fB/var/statmon/state\fR\fR .ad .br .sp .6 .RS 4n includes a number which changes during a reboot .RE .sp .ne 2 .mk .na \fB\fB/usr/include/rpcsvc/sm_inter.x\fR\fR .ad .br .sp .6 .RS 4n contains the rpcgen source code for the interface services provided by the statd daemon. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
