When CMAN determines that a node has failed, it communicates to other cluster-infrastructure components that the node has failed. fenced , when notified of the failure, fences the failed node. Other cluster-infrastructure components determine what actions to take — that is, they perform any recovery that needs to be done.
The only way to be 100% sure that your data is safe, is to fence the node using STONITH so we can be certain that the node is truly offline, before allowing the data to be accessed from another node. STONITH also has a role to play in the event that a clustered service cannot be stopped. In this case, the cluster uses
This chapter provides the procedures for configuring fencing using SCSI persistent reservations in a Red Hat cluster using the Conga configuration tool. SCSI persistent reservations provide the capability to control the access of each node to shared storage devices. Red Hat Cluster Suite employs SCSI persistent

Fencing is the disconnection of a node from the cluster's shared storage. Fencing cuts off I/O from shared storage, thus ensuring data integrity. This manual documents the configuration of fencing on clustered systems using High Availability Add-On and details the configuration of supported fence devices. 1. Fencing Pre-

You can use the ccs command to print a list of available fence devices and to print a list of options for each available fence type. You can also use the ccs command to print a list of fence devices currently configured for your cluster. To print a list of fence devices currently available for your cluster, execute the following
Configuring Fence Devices in a Red Hat Cluster. This document provides configuration examples that show the steps needed to configure fence devices in a Red Hat cluster using the Conga configuration tool. For general information about fencing and fence device configuration, see Configuring and Managing a Red Hat
Red Hat's documentation publication system recently went through an upgrade to enable speedier, more mobile-friendly content. We decided to re-evaluate our commenting platform to ensure that it meets your expectations and serves as an optimal feedback mechanism. During this redesign, we invite your input on
Testing the IPMI Fence Device Configuration. To check whether the configuration you have defined works as expected, you can use the fence_node to fence a node manually. The fence_node program reads the fencing settings from the cluster.conf file for the given node and then runs the configured fencing agent against
