Description Adam Litke 2022-06-28 13:27:25 UTC 
+++ This bug was initially created as a clone of Bug #2079781 +++

Description of problem:
When using storage api with filesystem volume mode the size increased for the fs overhead.
when trying to clone to block the clone fails because the target is smaller than source.

How reproducible:
100%

Steps to Reproduce:
1. Create a DV using storage api on filesystem volume mode.
2. Clone the DV with the same size to block.

Actual results:
clone fails:
 message: 'Error encountered while creating DataVolumes: Failed to create DataVolume:
        admission webhook "datavolume-validate.cdi.kubevirt.io" denied the request:  target
        resources requests storage size is smaller than the source'

Expected results:
Clone should succeed.

We have this also in 4.11

I am on it. Trying to reproduce.

Bartosz, were you able to reproduce?

Yes, and the test is already automated. This is the first commit in the PR https://github.com/kubevirt/containerized-data-importer/pull/2299.
Of course it needs to be backported to correct branch so it targets 4.10
