Description of problem:
Allocating a single large file on a PVC fails with ENOSPC eventhough nothing else has been written to it.
Version-Release number of selected component (if applicable):
How reproducible:
Create a PVC of 4GiB and allocate a 4GiB file in it.
Steps to Reproduce: ( With CNV setup , for example )
1. create a PVC of size 4GB
2. Create a VM with the above created PVC
3.
Actual results:
Allocating a single large file on a PVC fails with ENOSPC eventhough nothing else has been written to it.
Expected results:
It should be possible to allocate a single large file with the size of the requested PVC. A 4GiB PVC should be able to store a 4GiB file.

Irrelevant now for CNV, do we wish to fix this? I think a slight overhead is OK'ish.
