Is it an HCI deployment? I have had a similar problem and it was on an HCI deployment. The healing process get stuck for some reason that I don't know and it fills the space. What I did is reboot the node and the free space was there.

What version of ovirt are you using?

Look at the du output.

Thanks in advance for any suggestion(s).
