Hey all,<div><br></div><div>regarding 2-node clusters for a single service (e.g. HAproxy, in my case),</div><div>when now one node goes down, by server crash, or cable unplugged,</div><div>how does the other still functioning node actually know, that this is</div>
<div>not a split brain and can take over?</div><div><br></div><div>I also wonder how keepalived tool is managing that, which is magically working well so far,</div><div>but I'd like to migrate to pacemaker/corosync for the new services.</div>
<div><br></div><div>Many thanks,</div><div>Christian.</div>
