Proxmox rename node - big problem

[m3a2r1]

I've changed name for node and I'm totally stuck. Can't start any machine, can't get any storage.
It look like this:

proxmox is the old name, pve1 is the new name.
Anybody can help me?

I did it step by step and something get wrong

edit.
Now I'm thinking that was not step by step, firstly I've renamed host and changed /etc/hosts and rebooted pve, then I've renamed /var/lib/rrdcached/db content

Maybe it's too riskful to change node name if I've got a lot of vms ...

You run a cluster? And yes, renaming nodes in not recommended/supported.

See https://pve.proxmox.com/wiki/Cluster_Manager

No, I haven't got cluster. I think that renaming node with running cluster would be stupid and unreasonable

By the way, I've revert any changes, restart and I've got running pve with old name. I'm so scared now to change name again.

My PVE worked correctly only short time. Then the names of VMS/storage/etc dissapeared from GUI and I have no contact with VMs and storage.
What did I wrong? How to correct it?

Have one solution:
0.
!!! Caution !!!
/etc/pve/qemu-server/1**.conf should be backuped to be recovered after the removing obsoleted node
1. observe existing nodes:

ls /etc/pve/nodes
Debian-107-buster-64-minimal  lab02

2. then delete obsoleted node (in my case it was Debian-107-buster-64-minimal)

rm -r /etc/pve/nodes/Debian-107-buster-64-minimal/

3. finaly, recheck in UI
