That's correct.Ovirt knows and ensures that this NFS is available at all time and will take any actions to recover the situation.When you use autofs outside the oVirt, you still have that backup location and also it will umount when not in use. Best Regards,Strahil Nikolov On Sat, Jun 5,

I could be mistaken, but I think the issue is that ovirt engine believes the NFS domain is mandatory for all hypervisor hosts unless you put the storage domain into 'maintenance' mode. It will notice its down and start trying to fence the offending hypervisors which in turn tries to migrate VMs to

Exactly. Ovirt will monitor storage only if it knows about it.I would use autofs or systemd's '.mount' + '.automount' unit files to automatically mount and umount the NFS. In worst case scenario, you will have only several stale NFS mount points (if using the hard option) and those most of the

When I stopped the NFS service, I was connect to a VM over ssh. I was also connected to one of the physical hosts over ssh, and was running top. I observed that server load continued to increase over time on the physical host. Several of the VMs (perhaps all?), including the one I was connected
