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