       lockd(1M)                                                  lockd(1M)


       NAME
             lockd - network lock daemon

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

       DESCRIPTION
             The lockd command 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,
             then it sends SIGLOST to a process.

       USAGE
             The lockd daemon is automatically invoked in run level 3.

             The following options are available to the lockd command:

             -t timeout
                   Use timeout seconds as the interval instead of the
                   default value (25 seconds) to retransmit lock request to
                   the remote server.

             -g graceperiod
                   Use graceperiod seconds as the grace period duration
                   instead of the default value (25 seconds).

             Only a privileged user can execute this command.
