@cnzf1 The problem is with the attacher - in the attacher.yaml - update the image tag to new one image: quay.io/k8scsi/csi-attacher:v3.1.0

Hi we have same issue, attacher, provisioner, csi-s3, secret and storage class are on namespace kube-system

PVC is on another namespace

on the attacher we have this error:

on the pod we get this error:

we delete the attacher, change

and re-create all

the PVC is Bound and created on the S3 platform, the only issue is to attached it to the container on creation

any idea?

Hi, we solve the issue by changing the ClusterRole of the attacher from

- apiGroups: ["storage.k8s.io"]
    resources: ["volumeattachments"]
    verbs: ["get", "list", "watch", "update", "patch"]

to

- apiGroups: ["storage.k8s.io"]
    resources: ["*"]
    verbs: ["get", "list", "watch", "update", "patch"]
