Deployment of hybrid cluster failed

[Tinwen]

Hello everyone, I have encountered a problem. I am trying to deploy a hybrid cluster. There are a total of 6 virtual machines, 101-106; The two PVE versions are different; Firstly, use 101 to build Cluster 1. Adding 102-103 succeeded, then adding 104 succeeded, and finally adding 105 failed, causing the entire cluster to crash; One PVE version is 7.4-3, and the other PVE version is 8.3-4; After the crash, the cluster status displayed an error. The log shows that files added to the virtual machines etc/ve/local in the cluster are missing. What is the reason?

Proxmox does not support ARM: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_system_requirements
Whatever you are running on ARM is not PVE as created and supported by Proxmox. What fork or copy are you running? Where did it come? Who maintains it?

I was wrong, it's two x86 architectures, just different versions

Two-node clusters are always problematic; use a QDevice to ensure quorum: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_quorum
Different version can also lead to problems; update the 7.4-3 to the latest 7.4 (-12 or -14?) and then to the latest 8: https://pve.proxmox.com/wiki/Upgrade_from_7_to_8 (or remove this node, create a new PVE 8.2-4 node with a new iP and new name and add that to the cluster).
