NAME
     statd - network status monitor

SYNOPSIS
     /usr/lib/nfs/statd


DESCRIPTION
     statd is an intermediate version of the status  monitor.  It
     interacts  with  lockd(1M) to provide the crash and recovery
     functions for the locking services on NFS. 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 inform  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.


     lockd  is  started  by  automountd(1M),  mountnfs(1M),  and
     share(1M) if NFS automounts are needed.

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


     The statd service  is  managed  by  the  service  management
     facility, smf(5), under the service identifier:

       svc:/network/nfs/status




     Administrative actions on this service,  such  as  enabling,
     disabling,  or  requesting  restart,  can be performed using
     svcadm(1M). The service's status can be  queried  using  the
     svcs(1) command.


     If it is disabled, it  will  be  enabled  by  mountnfs(1M),
     sharenfs(1M),     and     automountd(1M)     unless     its
     application/autoenable property is set to false.
