lockd(IM) lockd(IM)
NAME
lockd - process network lock daemon
SYNOPSIS
/ etc/ rpc .lockd [ -t timeout] [ -g grace period ]
DESCRIPTION
lockd is a network lock daemon that processes lock requests that
are sent either locally by the kernel or remotely by another lock
daemon. lockd forwards lock requests for remote data to the
lock daemon at the server site through the RPC/XDR package.
lockd then requests the status monitor daemon, statd(1M), for
monitor service. The reply to the lock request is not sent to the
kernel until the status monitor daemon and the lock daemon at the
server site replies.
If either the status monitor daemon or the lock daemon at the
server site 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 each
lockd at a client site to submit reclaim requests. Each lockd at
a client site, on the other hand, is notified by the s tat d of the
server recovery and promptly resubmits a previously granted lock
request. If lockd fails to secure a previously granted lock at the
server site, lockd sends SIGTERM to a process.
FLAG OPTIONS
The following flag options are interpreted by lockd:
-t timeout Use timeout (seconds) as the interval instead of the
default value (15 seconds) to retransmit a lock request
to the remote server.
-g grace period
Use grace period (seconds) as the grace period duration
instead of the default value (45 seconds).
