Two-Node High Availability Cluster

[michael.v]

Hey everyone,

I found an article on Proxmox for setting up a Two-Node HA Cluster using a shared quorum disk, but it's about older versions of PVE, not the latest. Is this still possible when using shared storage with two nodes? They will use a direct-attached SAS SAN to provide block/LUN storage to the hosts. If this is not an option anymore, do we need to have another node (VM or physical node) for which the QDisk (Corosync Host) daemon can run on for HA witness (https://pve.proxmox.com/wiki/Cluster_Manager#_quorum)?

Appreciate your feedback!

@michael.v, Yes, it still work, you can reference it from https://pve.proxmox.com/wiki/Cluster_Manager#_corosync_external_vote_support

Thanks, I can see the QDevice is supported and mentioned there but not the Quorum shared disk like the older article. Is the quorum shared disk still referenced anywhere or supported?

Sorry, Quorum shard disk as I know is an outdated solution and not supported by Proxmox VE, even the file /etc/pve/cluster.conf now does not exist in /etc/pve folder.

Thanks, David,

That makes sense. That’s all I needed to confirm! I will plan to do a VM on a separate host that can be the QDevice to provide HA quorum.
