Proxmox Cluster as HA NFS server?

[raytracy]

Is it possible to setup HA nfs server within exist proxmox cluster?

My idea design will be:

• 3 nodes proxmox clustered
• two nodes will run ZFS with DRBD for both cluster storage and KVM virtualization
• 3rd node will run KVM as virtualization node and quoram only (no local storage)
• Maybe joint more node to cluster for virtualization node only (no local storage)

I am planning export nfs share from DRDB cluster to 3rd (or later) node and expect this nfs still maintain HA functionality.

Does it possible to manage above configuration via GUI interface?
Is there any reference case or configuration?
