Introduction

xiRAID Classic can operate within a High Availability (HA) cluster, ensuring data integrity and availability for users by distributing data and system components across two nodes. To set up a High Availability cluster for xiRAID Classic, configure and connect two cluster nodes to a shared set of drives. In case of a node failure, the xiRAID Classic components can migrate to other operational nodes within the cluster, maintaining continuous operations without disruption.

The management of xiRAID Classic components within an HA cluster is conducted by the Pacemaker cluster manager, which coordinates failover mechanisms and ensures transitions of RAIDs between nodes. File synchronization among clustered nodes can be facilitated by the Csync² utility, which includes conflict detection, file deletion detection, and update handling. However, users have the option to choose any other utility for this purpose.

This guide provides instructions on integrating xiRAID into an existing Pacemaker cluster.
