statd, rpc.statd — network status monitor




statd is an RPC server. It interacts with lockd to provide the crash and recovery functions for the locking services on NFS (see lockd(1M)).

statd keeps track of the clients with processes which hold locks on a server. When the server reboots after a crash, statd sends a message to the statd on each client indicating that the server has rebooted. The client statd processes then informs the lockd on the client that the server has rebooted. The client lockd then attempts to reclaim the lock(s) from the server.

statd on the client host also informs the statd on the server(s) holding locks for the client when the client has rebooted. In this case, the statd on the server informs its lockd that all locks held by the rebooting client should be released, allowing other processes to lock those files.


statd recognizes the following options and command-line arguments:

-l log_file

This is an obsolete option. All messages and errors are logged to /var/nfs/rpc.statd.log.


The crash of a server is only detected upon its recovery.



lists hosts and network addresses to be contacted after a reboot


lists hosts and network addresses that could not be contacted after last reboot


includes a number which changes during a reboot


statd was developed by Sun Microsystems, Inc.
