The cluster will continue operating without service interruption. Network services will be unaffected as the
cluster's virtual IP address is assigned to the primary node.
While the secondary node is offline, the cluster will no longer be fault-tolerant. A subsequent failure of the
primary node will leave the cluster inoperable.
To recover the cluster, the secondary node must be brought back online. If the node has experienced only a
temporary outage and has the same cluster configuration, the cluster will automatically repair itself.
Replication will update the secondary node with any database or configuration changes that were made on
the primary node while the secondary node was offline.
If the secondary node was replaced due to a hardware failure then the cluster must be destroyed and
rebuilt. See
in this state.

Email Notification

In addition to sending syslog messages, Amigopod can also send email alerts to operators with
administrator access if a high-availability cluster enters a failover state. This feature requires that each
high-availability node have a valid SMTP configuration, and that each operator login is configured with an
email address.

Cluster Status

The current status of the cluster is shown at the top of each page that is related to High Availability
Services. for an explanation of each possible status, and the recommended action to take, if any.

The secondary node has taken over the cluster services because the primary node is down.
 A failover has occurred. The cluster must be recovered to resume fault-tolerant operation.
 Ensure the primary node is back online.
The secondary node has taken over the cluster services. The primary node is back online, but the
cluster needs to be recovered.
 A failover has occurred. The cluster must be recovered to resume fault-tolerant operation.
