 | Resource quotas may not work properly with the CSI PowerFlex driver. PowerFlex is only able to assign storage in 8Gi chunks, so if a create volume call is made with a size not divisible by 8Gi, CSI-PowerFlex will round up to the next 8Gi boundary when it provisions storage -- however, the resource quota will not record this size but rather the original size in the create request. This means that, for example, if a 10Gi resource quota is set, and a user provisions 10 1Gi PVCs, 80Gi of storage will actually be allocated, which is well over the amount specified in the resource quota. | For now, users should only provision volumes in 8Gi-divisible chunks if they want to use resource quotas. |
