Hi,
I deployed a oVirt (4.3.10) cluster with HostedEngine and GlusterFS volumes
(engine, vmstore, data), the glusterfs cluster on node1/node2/node3, and the
engine vm can be running on those 3 nodes.
Then I added a 4th nodes into cluster.
But, when I operates on Eninge Web Portal, it's always reports 503 error, then
I checked `hsoted-engine --vm-status`, see below:
```

```
Then, wait a moment, can access web portal again, and check the hosts status,
alway reports one or more hosts with label `unavaiable as HA score`, but it
will dispear later.
And I found, sometimes the engine vm will migrated to another nodes whill this
problem occur.
So, seems the HostedEngine is not stable, always occur this problem, could you
please help me with this ? Thanks!
