Cause:
Alibaba Cloud supports only Disk volumes larger than 20 GiB.
Attempt to dynamically provision a new volume for a PersistentVolumeClaim (PVC) smaller than 20GiB fails and such PVC is Pending forever.
Consequence:
Small PVCs, created e.g. by a StatefulSet or Helm charts are Pending forever and applications that want to use them can't start.
Fix:
OpenShift will automatically increase the volume size and it will provision volumes at least with 20 GiB in size.
Result:
Volumes for small PVCs are dynamically provisioned and applications can start. At the same time, operational costs of such application may increase, as 20GiB volumes are created (and charged for) when an app uses only a fraction of it.
