[Users] Iso_domain

Dear all, How can I remove a iso from the iso domain? Can I just delete the image from /var/lib/exports/iso/50cf24a4-d1ef-4105-a9a5-b81d91339175/images/11111111-1111-1111-1111-111111111111 and expect ovirt to know the image is gone and adapt the gui and database accordenly or...? Kind regards, Koen
