Owner of qcow2 is nobody:nobody. I added owner and group information, but still error is the same:cannot chown /var/lib/cloudOver/storages/core/dbedb2cee9444107ab505e58045bc66a_eedf0e1bf4974d709d32269fe4fd594e to (0, 0): Operation not permitted
With defined owner and group even qcow2 images fail. Without it, qcow2 works fine.

all parent directories for this pool have rx permissions for group and other. I'm wondering why error is "operation not permitted" when the image file doesn't exist in filesystem? All existing files in this directory were created with qcow2 format.
For now, probably I'll create temporary solution for this - I convert all files as qcow2 during upload or create actions in cloud.
