    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 pro-
           cesses 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)	 hold-
           ing  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), mount_nfs(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 mount_nfs(1M),	share_nfs(1M),
           and automountd(1M) unless  its	     application/auto_enable  property
           is set to false.
