Hi Robert, there were serveral issues with ownership in ovirt, for example see; https://bugzilla.redhat.com/show_bug.cgi?id=1666795 Maybe you're encountering these issues during the upgrade process. Also if you're using gluster as backend storage, there might be some permission issues in the 6.7 or below branches. not sure about the newest version's.

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.

Cheers,

Robert O'Kane
