Hello,  i have already experiences with install a standalone Nextcloud. But now i will run a HA-Nextcloud on 2 different locations, with 2 internet connections running on two RPIs. If one node have no internet-connect or no power in a case of a blackout, so the other have to do the job automatically. I cant imagine that this constallation is so exotic, that it gives no how-to for that.  Do i need DRBD, Pacemaker, Heartbeat and a Reverse-Proxy? And how do i configurate all of this?  Please help
