slubmanFirst day tests were not all positive.1. There was some instability with my <a href="https://social.linux.pizza/tags/wireguard" class="mention hashtag" rel="nofollow noopener" target="_blank">#wireguard</a> vpn.For the time being, I think I solved this issue by disabling the HA, particularly <a href="https://social.linux.pizza/tags/keepalived" class="mention hashtag" rel="nofollow noopener" target="_blank">#keepalived</a> . I'll study this issue in depth later, as I might ditch the HA 🤔 2. There was some misconfigurations, of course it was the <a href="https://social.linux.pizza/tags/DNS" class="mention hashtag" rel="nofollow noopener" target="_blank">#DNS</a> that was causing a lot of issues. There I also disabled the HA, but the new router does allow me to configure more than one DNS for the LAN clients, so HA might not be needed anymore 🤔 3. The static routing for <a href="https://social.linux.pizza/tags/IPv6" class="mention hashtag" rel="nofollow noopener" target="_blank">#IPv6</a> works differently with the new router, so I had to adapt it.With all these correctives actions, it's time for a second day of tests 🤞🏾<a href="https://social.linux.pizza/tags/homelab" class="mention hashtag" rel="nofollow noopener" target="_blank">#homelab</a>

ItzTrain<a href="https://fosstodon.org/@OGSH" class="u-url mention" rel="nofollow noopener" target="_blank">@OGSH</a> No there was one clear master, but every time I stopped the process there would be no failover. If I stop the process and then restarted <a href="https://hachyderm.io/tags/keepalived" class="mention hashtag" rel="nofollow noopener" target="_blank">#keepalived</a> , then it would fail over.. I think. I thought it would be in real time, but maybe that's not how it works. It was also the priority thing plus the weight thing threw me off. Couldn't find a good example of it either.

HabrУмный дом на openHAB+MQTT+Arduino. Часть 1: КластерИзначально была мысль повысить доступность openHAB средствами виртуализации. Ставим два гипервизора, настраиваем High availability, при отказе хоста виртуалка с openHAB перезапустится на соседнем сервере. И все бы ничего, но для работы HA нужно общее хранилище. Какой-то NAS допустим у меня есть, но выход его из строя даже более вероятен, чем отказ хоста. А городить что-то на DRBD или подобном не хотелось. Поэтому было решено кластеризовать openHAB другим способом. см. рисунок ниже<a href="https://habr.com/ru/articles/804659/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/articles/804659/</a><a href="https://zhub.link/tags/openhab" class="mention hashtag" rel="nofollow noopener" target="_blank">#openhab</a> <a href="https://zhub.link/tags/mqtt" class="mention hashtag" rel="nofollow noopener" target="_blank">#mqtt</a> <a href="https://zhub.link/tags/ethernet" class="mention hashtag" rel="nofollow noopener" target="_blank">#ethernet</a> <a href="https://zhub.link/tags/arduino" class="mention hashtag" rel="nofollow noopener" target="_blank">#arduino</a> <a href="https://zhub.link/tags/cluster" class="mention hashtag" rel="nofollow noopener" target="_blank">#cluster</a> <a href="https://zhub.link/tags/vrrp" class="mention hashtag" rel="nofollow noopener" target="_blank">#vrrp</a> <a href="https://zhub.link/tags/lsyncd" class="mention hashtag" rel="nofollow noopener" target="_blank">#lsyncd</a> <a href="https://zhub.link/tags/mosquito" class="mention hashtag" rel="nofollow noopener" target="_blank">#mosquito</a> <a href="https://zhub.link/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#linux</a> <a href="https://zhub.link/tags/keepalived" class="mention hashtag" rel="nofollow noopener" target="_blank">#keepalived</a>
