I'm unable to get PVC working on a new eks cluster. I see the error Waiting for a volume to be created either by the external provisioner 'ebs.csi.aws.com' or manually by the system administrator. If volume creation is delayed, please verify that the provisioner is running and correctly registered. under PVC.

As a result my postgresql pod hasn't started. This is a new EKS cluster and I'm not sure if I missed something when setting it up.

Any idea why the PVC isn't working?

StorageClass:

[ec2-user@ip-10-15-1-155 manageiq-operator]$ kubectl get sc
NAME            PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE

Same as yours with v1.27.15-eks In 2024. At first.I consider it deprecated that AWS EKS Document not mention any word about gp2.

End Up I follow "Store app data" within docs and setup EBS storage class. Then It Works.

Finally realized that it's beacuse I haven't setting up Amazon EBS CSI driver and IAM role for it cuz provisioner: kubernetes.io/aws-ebs depends on it.
