[ovirt-users] Hosts been evacuated unnecessarily

[FERNANDO FREDIANI]

Hello folks.

Ou oVirt (4.1.7.3-1.el7.centos) which runs in one Datacenter and 
controls Nodes locally and also remotelly lost communication with the 
remote Nodes in another Datacenter.
To this point nothing wrong as the Nodes can continue working as 
expected and running their Virtual Machines each without dependency of 
the oVirt Engine.

What happened at some point is that when the communication between 
Engine and Hosts came back Hosts in the remote Datacenter got confused 
and initiated a Live Migration of ALL VMs from one of the hosts to 
another. I had also to restart vdsmd agent on all Hosts in order to get 
sanity my environment.

What adds up even more strangeness to this scenario is that one of the 
Hosts affected by the need of restarting VDSM doesn't belong to the same 
Cluster as the others and had to have the vdsmd restarted.

I understand the Hosts can survive without the Engine online with 
reduced possibilities but can communicated between them, but without 
affecting the VMs or even needing to do what happened in this scenario.

Am I wrong on any of the assumptions ?

Fernando
