cmannotifyd

cmannotifyd(8)						     CMAN Notification Daemon						    cmannotifyd(8)

NAME

       cmannotifyd - CMAN Notification Daemon

SYNOPSIS

       cmannotifyd [-f] [-d]

DESCRIPTION

       The cmannotifyd daemon talks to CMAN and provides a mechanism to notify external entities about cluster changes.

       CMAN dispatches 3 kind of notifications:

       - CMAN_REASON_TRY_SHUTDOWN when cman requests to all clients if it is allowed to shutdown.

       - CMAN_REASON_STATECHANGE when cman detects a node joining or leaving the cluster.

       - CMAN_REASON_CONFIG_UPDATE when a configuration change event has been detected/requested.

       These notifications are then dispatched to the shell script cman_notify in the environment variable CMAN_NOTIFICATION.

       cman_notify will then execute all the scripts in the configured notification directory (default: /etc/cluster/cman-notify.d) passing a very
       minimal set of envvars including, of course, the CMAN_NOTIFICATION= type.  The execution order is set by the filename as shown by "LC_ALL=C
       ls -las".

       cmannotifyd logs are stored in the default log file (/var/log/cluster/cmannotifyd.log).

       cman_notify  logs are stored in the default log file (/var/log/cluster/cman_notify.log). By default the output from the scripts executed by
       cman_notify is redirected to /dev/null.	Users can either set CMAN_NOTIFICATION_DEBUG=1 in their environment or set proper debug configura-
       tion in cluster.conf to redirect scripts output to the cman_notify log file.

NOTES

       cmannotifyd does not block on cman_notify nor check the exit status of the script.

       Notifications are dispatched in the same order as they arrive, one by one.

       CMAN_REASON_TRY_SHUTDOWN  is  passed  to  scripts  for information only, they can not influence cman's decsion about whether or not to shut
       down.

       CMAN_REASON_STATECHANGE also implies CMAN_NOTIFICATION_QUORUM exported in the environment. CMAN_NOTIFICATION_QUORUM will be set to 1  (when
       the node is part of a quorate cluster) or 0 (otherwise).

       A template for cman_notify scripts can be found in the doc/ directory.

OPTIONS

       -f     Run in the foreground (do not fork / daemonize).

       -d     Enable debug output.
