How to Deploy an existing EBS volume to EKS PVC?-CodePudding

I have an existing ebs volume in AWS with data on it. I need to create a PVC in order to use it in my pods. Following this guide: https://medium.com/pablo-perez/launching-a-pod-with-an-existing-ebs-volume-mounted-in-k8s-7b5506fa7fa3

persistentvolume.yaml

Status is pending (waiting to the consumer to be attached) - but it should already be provisioned.

CodePudding user response：

try fsType "xfs" instead of ext4

CodePudding user response：

The "waiting for consumer" message suggests that your StorageClass has its volumeBindingMode set to waitForFirstConsumer.

The default value for this setting is Immediate: as soon as you register a PVC, your volume provisioner would provision a new volume.

The waitForFirstConsumer on the other hand would wait for a Pod to request usage for said PVC, before the provisioning a volume.

The messages and behavior you're seeing here sound normal. You may create a Deployment mounting that volume, to confirm provisioning works as expected.
