did you restart your nfs service or reboot your nfs host during the upgrade progress ? if you did, what's the webadmin portal's storage domain's status at the time ? what i'm suspecting is that you were restarting nfs while ovirt-engine is using it. 2017-05-11 2:02 GMT+08:00 Jason Keltz <jas(a)cse.yorku.ca&gt;: > Hi. > > I recently upgraded my oVirt infrastructure to the latest > 4.1.1.8-1.el7.centos, which went smoothly.
