hard storage limit csi driver for 3par

When trying to create a persistentvolumeclaim of 100MB where 3par is the underlying storage. The PVC creation is failing. There appears to be a hard limit of 256MB.  Wondering why there is a hard limit rather than an auto-increase to the minimum size. This appears to be the case with other CSI drivers

Hello Anto,

I think the present value for the pvc is set to 256MB. Please try to edit the 'pvc***.yml' file and set the storage class to 100MB.

Hi,

I don't think that will work as 3par itself as a minimum volume size of 256MB. The issue I have encountered is that 3par csi driver should be able to create a volume with the minimum size even f the volume is not the minimum specified in value file.

i.e i

have a volume size in my chart of 100MB but the 3par csi driver is capable of creating as 256MB it's the minimum size.
