Light weight PVC is getting created more than max PVC size #1235

Closed saurabhwani5 closed 1 month ago

saurabhwani5 commented 1 month ago

Describe the bug

Max allowed PVC size is 953673728Gi , where as for light weight volume PVC is getting created of size more than that

How to Reproduce?

Please list the steps to help development teams reproduce the behavior

  1. Create PVC as following : 
    
[root@ocp pr1226]# cat lw.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: scale-advance-pvc-1
spec:
accessModes:
- ReadWriteMany
resources:
requests:
  storage: 1953673729Gi
storageClassName: ibm-spectrum-scale-csi-lw

apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: name: ibm-spectrum-scale-csi-lw provisioner: spectrumscale.csi.ibm.com parameters: volBackendFs: "fs0" volDirBasePath: "LW" reclaimPolicy: Delete allowVolumeExpansion: true [root@ocp pr1226]# oc apply -f lw.yaml Warning: spec.resources.requests[storage]: fractional byte value "1953673729Gi" is invalid, must be an integer persistentvolumeclaim/scale-advance-pvc-1 created storageclass.storage.k8s.io/ibm-spectrum-scale-csi-lw created

2. Check PVC is getting created

[root@ocp pr1226]# oc get pvc -w NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS VOLUMEATTRIBUTESCLASS AGE scale-advance-pvc-1 Pending ibm-spectrum-scale-csi-lw 3s scale-advance-pvc-1 Pending ibm-spectrum-scale-csi-lw 8s scale-advance-pvc-1 Pending pvc-6ecdebcf-05aa-4d39-be6a-4c7bac2066eb 0 ibm-spectrum-scale-csi-lw 12s scale-advance-pvc-1 Bound pvc-6ecdebcf-05aa-4d39-be6a-4c7bac2066eb 1953673729Gi RWX ibm-spectrum-scale-csi-lw 12s

3. Check PVC description

[root@ocp pr1226]# oc describe pvc Name: scale-advance-pvc-1 Namespace: ibm-spectrum-scale-csi StorageClass: ibm-spectrum-scale-csi-lw Status: Bound Volume: pvc-6ecdebcf-05aa-4d39-be6a-4c7bac2066eb Labels: Annotations: pv.kubernetes.io/bind-completed: yes pv.kubernetes.io/bound-by-controller: yes volume.beta.kubernetes.io/storage-provisioner: spectrumscale.csi.ibm.com volume.kubernetes.io/storage-provisioner: spectrumscale.csi.ibm.com Finalizers: [kubernetes.io/pvc-protection] Capacity: 1953673729Gi Access Modes: RWX VolumeMode: Filesystem Used By: Events: Type Reason Age From Message

## Expected behavior

Light weight volume should not be created more than the max pvc size which is 953673728Gi
