lockd(1M)                         NFS 5.4.2                        lockd(1M)


NAME
       lockd - network lock server

SYNOPSIS
       /usr/etc/rpc.lockd [ -t timeout ] [ -g graceperiod ]

DESCRIPTION
       Lockd processes lock requests that are sent remotely by another lock
       server (daemon).  Lockd forwards lock requests for remote data to the
       server site's lock server through the RPC/XDR(3N) package.  Lockd
       then requests the status monitor server, statd(1M), for monitor
       service.  The reply to the lock request will not be sent to the
       kernel until the status server and the server site's lock server have
       replied.

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

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

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

       -g graceperiod
                 Lockd uses graceperiod (seconds) as the grace period
                 duration instead of the default value (15 seconds).
