Hi All,
first of all to say many thanks to all forum contributors for real good tips, hints and explanations! I´m new with proxmox and i am now facing a serious problem.
Long story short:
- Installed Proxmox ona a single host and played around with VMs and containers.
- Thought that two servers are better than one and installed the second node (both 5.1)
- created a cluster but am unable to create VMs or CTs, the Node Field is empty. (I have NO central storage)
- No i want to get rid of the cluster and continue playing with one host. But when i shutdown the second node to remove it with "pvecm delnode proxmox2" it says "cluster not ready - no quorum?"

How can i go back to a single host and completely remove the second node and the cluster services?

With offline node2 pvecm status says

Do you have any hints oder ideas for that? The playground got serious in the meanwhile and i don´t want to loose the existing VMs on the first host. Or should i backup all VMs and start from scratch?
Thank you for reading and your support!
Best Greetings
