Hello @All, This has happened to us for the first time and only on One VM. I believe it happened with the switch from Fuse to "LibgfApi" in Ovirt. I was using LibgfApiSupported=True on 4.2.8 . I upgraded to 4.3.8 and did NOT restart all of my VMs (30+) but only some VMs, no problem. Eventually I noticed that LibgfApiSupported=False and reset it to True. The VM was Running WindowsServer2016 and we did a Cold-Reboot (not VM Restart). It did not come back online due to "Invalid Volume" which was eventually due to the IMAGEs (Boot and Data) being user:group=root but not the meta,lease or directory. Nor any other VM have/had this problem but they were (if at all) completely stopped and restarted. I am looking for another VM that has not yet been restarted to test this theory. I thought this would be interesting for others looking into this problem. (I will ask my Colleague next week what he means with Cold-Reboot vs Warm-reboot....) Stay Healthy.
