<div dir="ltr">We currently use kea in an HA (slightly unsupported setup) and I believe 1.4 will include the rest of the missing pieces for HA (due in a few weeks). We have 3 servers in a galera mysql cluster and two dhcp server. We are double VRRP'ing between them so both IPs always stay up. Using 1.3, while some metrics have been screwed up, the core functionality has been rock solid for ~6 months.</div><br><div class="gmail_quote"><div dir="ltr">On Thu, May 10, 2018 at 9:24 AM Sutherland, Robert <<a href="mailto:Robert.B.Sutherland@windstream.com">Robert.B.Sutherland@windstream.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p><span lang="EN">Hello,<br>
<br>
I understood that Kea still does not have failover or any other type of high availability (I have version 1.1.0 and use memfile).<br>
<br>
Case 1: If I use only static lease (reservations) and keep two servers with the same configuration file, would it work as high availability ?.<br>
<br>
Case 2: If I use a pool on each server, would it be a way of high availability? :<br>
server1 = {"pool": "192.168.0.50 - 192.168.0.100"}<br>
server2 = {"pool": "192.168.0.101 - 192.168.0.200"}</span><u></u><u></u></p>
