1374 - RedApp: Azure Kubernetes error "Agent unresponsive"

If communication is temporarily lost between a Redstor Kubernetes Agent and the Redstor backend, an error "Agent unresponsive" presents.

 

 

The issue may be caused by one of the following:

1. Agent unable to communicate with Azure Service Bus

To resolve this, confirm that the node the Redstor Kubernetes Agent deployment is running on can connect to the Azure Service Bus.

• ZA: hostname rks-za.servicebus.windows.net, ports 5671 and 443
• UK: hostname rks-uk.servicebus.windows.net, ports 5671 and 443

 

2. The redstor-k8s-rka deployment (in the redstor-k8s-* namespace) is experiencing issues

The cluster may have stopped due to insufficient resources/nodes. To resolve this, increase resources by stopping/removing unused services, or adding new nodes/resources.

If the redstor-k8s-rka deployment is in an error state, consider the following:

• Consult the event history, as well as the logs of the "redstor-k8s-rka-*" pod, to aid in troubleshooting.
• Restart the deployment.
• Remove the cluster from the RedApp and re-add it.
