Troubleshooting stacks that include the Amazon ParallelCluster custom resource

With an Amazon ParallelCluster custom resource, CloudFormation deploys a cluster from a new, separate stack. You can monitor cluster creation by taking the following steps:

  1. Navigate to CloudFormation in the Amazon Web Services Management Console and choose Stacks in the navigation pane.

  2. Choose the stack with the name that you defined for the cluster name.

  3. If the stack state is ROLLBACK_COMPLETE, an error occurred during cluster creation.

  4. Choose Stack details, and choose the Events tab.

  5. Search Events on Logical ID for the name that you defined for the cluster name. It has a Status reason that gives a reason for an issue.

  6. You can also choose the Stacks drop down menu, and then Deleted to see the list of deleted stacks. Select the stack with the cluster name and view Events for more details.

  7. To view the output from the custom resource provider that manages the cluster, select the stack with the Description "Amazon ParallelCluster Cluster Custom Resource." Choose the Resources tab, find the resource with Logical ID PclusterCfnFunctionLogGroup, and follow the given link. View the log streams that show the Lambda debug output.

  8. To troubleshoot the cluster, see Amazon ParallelCluster troubleshooting.
