Description Matthew Robson 2019-03-13 14:30:03 UTC

Description of problem:

Trying to resize a PVC from the console always fails if the project has a limitrange set.

Error: "Can't be greater than ."

If you delete the limitrange, the resize works without issue.

Reported here: https://github.com/openshift/origin-web-console/issues/3096

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

3.11.59

How reproducible:

Always

Steps to Reproduce:
1. Create PVC
2. Resize from oc edit pvc works
3. Create new PVC
4. Resize from PVC -> Actions -> Expand PVC
5. Error: "Can't be greater than ."
6. oc delete resourcequota --all
7. refresh console, still fails
8. oc delete LimitRange --all
9. Refresh and resize works

Actual results:

Resize fails with Error: "Can't be greater than ."


Expected results:

Successful resize

Ankush, are you able to look at this?

Comment 2 Ankush Behl 2019-03-15 18:44:45 UTC

Sam, Looking into this will update once the fix is available.

QE tried to reproduce the issue with steps

1. Create StorageClass with allowVolumeExpansion: true
oc get sc standard-testing -o yaml
allowVolumeExpansion: true
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    storageclass.beta.kubernetes.io/is-default-class: "false"
  creationTimestamp: 2019-03-26T03:20:11Z
  name: standard-testing
  resourceVersion: "39761"
  selfLink: /apis/storage.k8s.io/v1/storageclasses/standard-testing
  uid: 107d14f9-4f76-11e9-8b5a-fa163ede2042
parameters:
  fstype: xfs
provisioner: kubernetes.io/cinder
reclaimPolicy: Delete
volumeBindingMode: Immediate
2. Create Resource Quota 
apiVersion: v1
kind: ResourceQuota
metadata:
  name: quota-pvc-storage
spec:
  hard:
    persistentvolumeclaims: "1"
    requests.storage: "1Gi"
3. Create PVC using sc/standard-testing and set size to 500MiB, PVC will be bound
4. Goes to Storage -> mypvc -> Actions -> Expand PVC
5. Try to set Capacity to 500GiB, it will show error message " Storage quota will be exceeded. View Quota " and Expand button will be disabled, user can't expand to larger value
6. Try to set Capacity to 1GiB(quota limit), it can be expanded to 1GiB

this is checked on openshift v3.11.100

Didn't see error 'Can't be greater than .', will give another try on 3.11.59 tomorrow

Comment 8 Yadan Pei 2019-04-22 08:00:18 UTC

1. Create LimitRange 
# oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/limits/limits.yaml -n testproject
2. Create StorageClass with allowVolumeExpansion set to true
3. Create PVC using this storageclass
4. Goes to Storage -> mypvc -> Actions -> Expand PVC, there is error " Can't be greater than . " and not be able to expand PVC

This is reproduced on v3.11.59

Having LimitRange in project prevents user from expanding PVC. Having ResourceQuota doesn't affect the function

Comment 16 Yadan Pei 2019-06-14 09:07:13 UTC

1. Create StorageClass
allowVolumeExpansion: true
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: standard-testing
parameters:
  fstype: xfs
provisioner: kubernetes.io/aws-ebs
reclaimPolicy: Delete
volumeBindingMode: Immediate
2. Create LimitRange in project
oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/limits/limits.yaml -n testproject
3. Create PVC with capacity set as 500MiB
4. Expand PVC to 510MiB via Actions -> Expand PVC 

PVC can be successfully extended.

Verified on OpenShift Web Console:v3.11.117
