How does the Config-Checker utility work
The Config-Checker utility performs checks on the deployment environment to verify that the environment meets the requirements, before starting the primary server and media server deployments.
How does the Config-Checker works:
RetainReclaimPolicy check:
This check verifies that the storage classes used for PVC creation in the CR have reclaim policy as The check fails if any of the storage classes do not have the reclaim policy.
For more information, see the 'Persistent Volumes Reclaiming' section of the Kubernetes Documentation.
MinimumVolumeSize check:
This check verifies that the PVC storage capacity meets the minimum required volume size for each volume in the CR. The check fails if any of the volume capacity sizes does not meet the requirements.
Following are the minimum volume size requirements:
Primary server:
Data volume size: 30Gi
Catalog volume size: 100Gi
Log volume size: 30Gi
Media server:
Data volume size: 50Gi
Log volume size: 30Gi
Provisioner check:
EKS-specific only
Primary server: This will verify that the storage type provided is Amazon Elastic Block Store (Amazon EBS) for data and log volume. If any other driver type is used, the Config-Checker fails.
Media server: This will verify that the storage type provided is Amazon Elastic Block Store (Amazon EBS) for data and log volume. Config-Checker fails if this requirement is not met for media server.
AKS-specific only
This check verifies that the provisioner type used in defining the storage class is , for the volumes in Media servers. If not the Config-Checker will fail. This check verifies that the provisioner type used in defining the storage class is not for the volumes in Media servers. That is data and log volumes in case of Media server.
(EKS-specific only) AWS Load Balancer Controller add-on check:
This check verifies if the AWS Load Balancer Controller add-on is installed in the cluster. This load balancer controller is required for load balancer in the cluster. If this check fails, user must deploy the AWS Load Balancer Controller add-on
Cluster Autoscaler
This autoscaler is required for autoscaling in the cluster. If autoscaler is not configured, then Config-Checker displays a warning message and continues with the deployment of NetBackup servers.
(EKS-specific only) This check verifies if the AWS Autoscaler add-on is installed in the cluster. For more information, refer to 'Autoscaling' section of the Amazon EKS User Guide.
Volume expansion check:
This check verifies the storage class name given for Primary server data and log volume and for Media server data and log volumes has
AllowVolumeExpansion = true. If Config-Checker fails with this check then it gives a warning message and continues with deployment of NetBackup media servers.
