I had similar problems until I clicked "optimize volume for vmstore" in the admin GUI for each data volume. I'm not sure if this is what is causing your problem here but I'd recommend trying that first. It is suppose to be optimized by default but for some reason my ovirt 4.2 cockpit deploy did not apply those settings automatically.
