I saw in this thread that I can change vdsHeartbeatInSeconds (<a href="https://www.mail-archive.com/users@ovirt.org/msg41695.html" rel="noreferrer" target="_blank">https://www.mail-archive.com/<wbr>users@ovirt.org/msg41695.html</a>)<br>
but I don't really want to change it globally, just for the nodes in UK.<br>
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.<br></blockquote><div><br></div><div>To change it:</div><div>usr/share/ovirt-engine/dbscripts/engine-psql.sh -c "update vdc_options set option_value = 90 where option_name = 'vdsHeartbeatInSeconds'</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Or maybe its not best practice to have a cluster that far from the engine?<br></blockquote><div><br></div><div>We have an Engien in Israel managing hosts in Europe and the US.</div><div>Y.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
