Thanks for the info.

Indeed, using a raspy has been my first attempt, but I got stuck. Let’s try it again.

What are the recommended packages to install via apt on a raspi as a _diskless_ node? (The raspi should only serve as a quorum)

Do I need The LINBIT controller there?

Can I omit DRBD Reactor or Pacemaker with such a setup and stay with Proxmox-HA only? If not, I would like to setup Pacemaker as I can find more info (compared to DRBD Reactor) how to use it for other tasks as well.

What will the config look like in the end:

- one Controller VM on Proxmox under HA with a controller-db on the VM-disk?
- two independant Controller VMs, one on each PVE node, and shared storage DRBD disk (couldn’t do this with Proxmox HA only, right?)?
- How will the config look like for the VMs and probably the shared DRBD disk?
- How to config the raspi?

I really appreciate your feedback! Thanks again.

From my point of view - as a noob - information about DRBD versions (v8 available on common repos, v9 avail. on your LINBIT repo) as well as LINBIT software, their relation and interaction and most of all up-to-date configuration is somewhat not straight to catch, spreaded over different guides and a little bit foggy. As said: looking through the eyes as someone who just started with this.

And there is this from @kernat:

This is because DRBD Reactor uses DRBD’s quorum status to promote resources. Keepalived or Pacemaker could be used instead when you only have two nodes. You shouldn’t lose any data. Perhaps the writes are stuck in buffers somewhere. Try adding a sync to your script to test this: #!/bin/bash duartion=300 for((i0; i\<$duartion…

I really would favour this 2-node-Pacemaker-Proxmox-LinbitController setup. Maybe you have a How-to at hand, which I‘ve overlooked.
