Description Yanping Zhang 2020-12-15 12:28:19 UTC
Description of problem:
When expand pvc with an invalid size, clicking "Expand" gets no response.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Create a StorageClass 'expand-sc' with AllowVolumeExpansion set to true (if default SC doesn't support `allowVolumeExpansion`)
kind: StorageClass
apiVersion: storage.k8s.io/v1
  name: expand-sc
provisioner: kubernetes.io/aws-ebs
  fstype: xfs
reclaimPolicy: Delete
allowVolumeExpansion: true
volumeBindingMode: Immediate

2.Create a PVC using 'expand-sc'
3.When PVC becomes Bound,  go to Storage -> Persistent Volume Claims -> choose the PVC -> Actions -> Expand PVC
And set the new value to a smaller value or a negative number, eg -1, click "Expand"

Actual results:
3. There is no response after clicking.

Expected results:
3. Should show error info about the invalid value.

Checked on ocp 4.7 cluster with payload 4.7.0-0.nightly-2020-12-20-031835
When set the new value to a smaller value or a negative number on expand pvc modal, eg -1, click "Expand", there are alerts shown:
Danger alert:An error occurred
Error "Forbidden: field can not be less than previous value" for field "spec.resources.requests.storage".
Danger alert:An error occurred
Error "Invalid value: "-1Gi": must be greater than zero" for field "spec.resources[storage]".
The bug is fixed.
