We have an ovirt master (engine) host in Los Angeles and some remote
servers in the UK.
Normally they work fine, but when there is a heavy load on the UK
servers the management engine has problems with heartbeat and ends up
trying to restart the nodes.
I saw in this thread that I can change vdsHeartbeatInSeconds
(https://www.mail-archive.com/users@ovirt.org/msg41695.html)
but I don't really want to change it globally, just for the nodes in UK.
Also not sure how to get the current setting of that value, only how to
change it. How do I tell current value? I heard default is 30 seconds.
ovirt-engine-4.1.0.4-1.el7.centos.noarch
Or maybe its not best practice to have a cluster that far from the engine?

Perhaps the mgmt interface is used for traffic other than mgmt? On small
scale it's OK. For bigger scale and workloads, it's best to separate
traffic to dedicated NICs.

To change it:
usr/share/ovirt-engine/dbscripts/engine-psql.sh -c "update vdc_options set
option_value = 90 where option_name = 'vdsHeartbeatInSeconds'
ovirt-engine-4.1.0.4-1.el7.centos.noarch
I recommend upgrade, though not specifically due to the above issue.

We have an Engien in Israel managing hosts in Europe and the US.

thanks, we found when we switched to a different internet provider that
the network issues went away.
I'll look into upgrading, but it hard for us to keep up. We just got to
4.1.0 recently. :-)
