NAME
statd, rpc.statd — network status monitor
DESCRIPTION
statd
is an RPC server.
It interacts with
lockd
to provide the crash and recovery functions for the locking services
on NFS (see
lockd(1M)).
statd
keeps track of the clients with processes
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 informs 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) holding 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.
Options
statd
recognizes the following options and command-line arguments:
- -l log_file
This is an obsolete option. All messages and errors are logged to
/var/nfs/rpc.statd.log.
WARNINGS
The crash of a server is only detected upon its recovery.
