thank you,
why would we need a full corosync instance on RPI at all when it's not
supported and Qdevice is the better way for quorum ?
i.e. who is using full corosync on RPI at all and for what besides
quorum/whitness device?
i there a real purpose/benefit or does that wiki page simply describe
the "old way to go before qdevice did exist" ?

Using one with Qdevice and the corosync-qnetd service installed on it
is fine. See our documentation for it [0].
I updated the warning on the Wiki page to make it clearer why that
wiki page needs to be considered with care.

hello,
on this page https://pve.proxmox.com/wiki/Raspberry_Pi_as_third_node
there is told:
"Raspberry Pi as third node - This is only suited for testing or homelab
use. Never use it in a production environment! Simply use a QDevice!""
On https://pve.proxmox.com/wiki/Roadmap for Proxmox 5.4 there is the
following announcement:
QDevice support via `pvecm`
* primarily for small 2-node clusters adding a qdevice can help
mitigate the downside of not being able to reboot one node without
losing quorum (and thus the ability to make any changes in the
cluster) ** Can also help in clusters with a larger even number of
nodes by providing a tie-break vote.
* Integration into pvecm and PVE stack vastly simplifies adding a
qdevice (it was possible manually before as well)
my question is why there is information around which looks like
discouraging rasperry pi as third node for quorum, i.e. is a raspberry
pi with Qdevice (
->https://blog.jenningsga.com/proxmox-keeping-quorum-with-qdevices/ )
suitable for production use or not ?
