Node Failures in SMI Cluster Manager HA
Unlike a typical a Kubernetes cluster, the SMI Bare Metal HA consists of two AIO Bare Metal nodes running independently but synchronized in data using an underlying Distributed Replicated Block Device (DRBD) driver. The data synchronization happens in a specific manner with restrictions. Also, the DRBD utilizes the master keepalived for switchovers. You can run the synchronization for the SMI Cluster Manager HA from the Inception Server.
The subsequent sections provide more information about replacing failed nodes in SMI Bare Metal Cluster Manager HA mode.
