Hi I planning to setup a mirror setup with Ispconfig. Currently I have a multiserver setup. What I want to do is to create a load balancer with failover. So the traffic is split between my servers and if one of my servers goes down my second server will take over. Based on my research it seems to be a problem when using let's encrypt, especially when renewing the ssl certificate. I have read in this forum that I can share the let's encrypt folders with nfs, but it seems to be hard when using a cluster setup. I want the ssl certifictes to always be available, even if one server goes down. What will happen if the nfs server goes down? So my question is, is there any solution to use let's encrypt with a cluster setup without using nfs?
