@Piotr, assigning to you as it's on the VMIO side. When the controller creates the DataVolume, it should request a size slightly larger than the source disk. And I think it also concerns all block backend with a filesystem on top. @Fabien, This is an issue in CDI we have no ability to fix this in VMIO. Changing the component and assignee. In CNV-2.6 we will provide you with an API in CDIConfig where you can look up the recommended FS overhead value. You should grab this value and inflate the size of the DV/PVC yourself. |
