5 Node Cluster Unicast

[ChrisJM]

Hello,

We have tried adding a 5th node to our cluster but doesnt seem to want to work because it requires multicast - can someone please confirm that?

If that is correct is there a way to force unicast?

Yes,newer Proxmox versions use unicast, and there is no limitation(there is but it is more than 32/64 nodes if i'm not mistaken).
Multicast was needed for older proxmox clustering.
