Description Qin Ping 2020-08-24 03:33:24 UTC

Description of problem:
Need a more clear event message for ebs.csi.aws.com provisioner
Storage

Version-Release number of selected component (if applicable):
4.6.0-0.nightly-2020-08-23-185640

How reproducible:
Always

Steps to Reproduce:
1. Install an OCP4.6 cluster on AWS
2. Clone a storage class with ebs.csi.aws.com provisioner and Immediate bind mode.
3. Create a PVC with "RWX" or "ROX" access modes

Actual results:
PVC is in pending status and gets the following event:
Warning  ProvisioningFailed    <invalid> (x6 over <invalid>)  ebs.csi.aws.com_ip-10-0-49-238.us-east-2.compute.internal_003d900a-1a4e-43e0-ae5e-3da6bbe2c24d  failed to provision volume with StorageClass "gp2-csi-i": rpc error: code = InvalidArgument desc = Volume capabilities not supported

Expected results:
The event for internel provisioner "kubernetes.io/aws-ebs" is:
Warning  ProvisioningFailed  <invalid>  persistentvolume-controller  Failed to provision volume with StorageClass "gp2-i": invalid AccessModes [ReadWriteMany]: only AccessModes [ReadWriteOnce] are supported

The event for internal provisioner is more clear.

I've submitted [1] to address this issue upstream. Once it's merged we can backport it into our driver.
