statd

rpc.statd(8)						      System Manager's Manual						      rpc.statd(8)

NAME

       rpc.statd, statd - Network status monitor daemon

SYNOPSIS

       /usr/sbin/rpc.statd [-c]

OPTIONS

       Available only on TruCluster Server systems. This option starts the clusterwide network status daemon, which helps provide highly available
       NFS service. Do not use -c directly. Highly available NFS service is configured by default and typically does not require intervention.	If
       you do need to start the clusterwide network status daemon, use the CAA command, caa_start cluster_lockd.

	      For more information, see the TruCluster Server Administration manual.

DESCRIPTION

       The  rpc.statd daemon monitors the status of the client and server sites in response to a request made by the local rpc.lockd daemon.  When
       a site failure is detected, the rpc.statd daemon notifies the local rpc.lockd daemon, which then processes the recovery of the locked files
       or file regions.

RESTRICTIONS

       The crash of a site is only detected on its recovery.

FILES

       A directory created by the statd daemon.  Each file name in the directory is the host name of a client or server that the statd daemon will
       notify upon its recovery.  A backup directory created by the statd daemon.  A file created by the statd daemon to store its state number.
