NAME
     lockd - network lock daemon

SYNOPSIS
     /usr/lib/nfs/lockd [ -t timeout ] [ -g graceperiod ]

DESCRIPTION
     lockd processes lock requests that are either  sent  locally
     by  the  kernel  or  remotely by another lock daemon.  lockd
     forwards lock requests for remote data to the server  site's
     lock daemon through RPC/XDR.  lockd then requests the status
     monitor daemon, statd(1M), for monitor service.   The  reply
     to the lock request will not be sent to the kernel until the
     status  daemon  and  the  server  site's  lock  daemon  have
     replied.

     If either the status monitor or server site's lock daemon is
     unavailable,  the reply to a lock request for remote data is
     delayed until all daemons become available.

     When a server recovers, it waits for a grace period for  all
     client-site   lock   daemons  to  submit  reclaim  requests.
     Client-site lock daemons, on the other hand, are notified by
     the  status  monitor  daemon  of  the  server  recovery  and
     promptly resubmit previously granted lock  requests.   If  a
     lock daemon fails to secure a previously granted lock at the
     server site, the it sends SIGLOST to a process.

OPTIONS
     -t timeout
          Use timeout seconds as  the  interval  instead  of  the
          default  value  (15 seconds) to retransmit lock request
          to the remote server.

     -g graceperiod
          Use graceperiod seconds as the  grace  period  duration
          instead of the default value (45 seconds).
