# fence\_kdump\_send(8)

send kdump acknowlegement message to cluster nodes

## NAME

fence\_kdump\_send - send kdump acknowlegement message to cluster nodes

## SYNOPSIS

**fence\_kdump\_send** \[*OPTIONS\]*... \[NODE\]...

## DESCRIPTION

*fence\_kdump\_send* is a utility used to send messages that acknowledge that the node has entered the kdump crash recovery service. This utility is intended to be used the the *fence\_kdump* agent as a means detect that a failed node has entered the kdump crash recovery service. The *fence\_kdump\_send* utility is typically run from within the kdump kernel after a cluster node has encountered a kernel panic. Once the cluster node has entered the kdump crash recovery service, *fence\_kdump\_send* will periodically send messages to all cluster nodes. When the *fence\_kdump* agent receives a valid message from the failed node, fencing is complete.
