Sure! Right now, I only have a 500gb partition on each node shared over NFS, added as storage domains. This is on each node - so, currently 3. 

How can the storage cause a node to drop out?


Thanks, I got it.
All three links go down on load, which causes NFS to fail.

Can you check in the switch port configuration if there is some kind of Ethernet flow control enabled?
Can you try to modify the behavior by changing the settings of your host interfaces, e.g.
ethtool -A em1 autoneg off rx off tx off
or
ethtool -A em1 autoneg on rx on tx on
?

Also, if it helps, the hosts will sit there, quietly, for hours or
days before anything happens. They're up and working just fine. But
then, when I manually migrate a VM from one host to another, they
become completely inaccessible.


Can you share some details about your storage?
Maybe there is a feature used during live migration, which triggers the issue.

 
These are vanilla-as-possible CentOS7 nodes. Very basic ovirt install
and configuration.
