How to Delete Proxmox Cluster

All the commands I used in the video are for Version 4 and newer for Version 3, please consult the document above, I will also past the commands here.

Step 1. stop the cluster file system in /etc/pve/

# service pve-cluster stop

or if you use PVE 4.0 and newer

# systemctl stop pve-cluster

Step 2. start it again but forcing local mode
# pmxcfs -l

Step 3. remove the cluster config

Step 4. stop the cluster file system again
- on PVE 3.4 and earlier
# service pve-cluster stop
- on PVE 4.0 and newer
# systemctl stop pve-cluster

Step 5. (optional) you may have to delete the lockfile of the cluster filesystem:

Step 6. restart pve services (or reboot)
- on PVE 3.4 and older:
# service pve-cluster start
# service pvedaemon restart
# service pveproxy restart
# service pvestatd restart

- on pve 4.0 and newer
# systemctl start pve-cluster
# systemctl restart pvedaemon
# systemctl restart pveproxy
# systemctl restart pvestatd

Thanks!!! I've understand nothing from Your speech (my bad english). But copying commands gives the best result !!!

Thanks, even now this helps more than reading the proxmox docs

It's insane. 5 year old post by now, but this still works for version 8.2.4.

Thank you for the help. I really appreciate it.
Just a side note: the video would have been half of its size if you didn't keep repeating things you said before.

Thanks, very helpful and works on 6.4 as well. One question though, and while I have some experience with esxi, I'm pretty new to proxmox. My scenario is this, I have a current server (intel), and I want to make a new one (threadripper), I'd like to be able to copy VMs in between these two but I don't want issues when these two machines aren't running at the same time, so is it okay to make a cluster for this? I created the cluster on the new empty node, then tried adding the one with VMs and that didn't work, so I suppose I should do this the other way around. I just would like to be able to copy or move VMs from one node to the other but don't want both node to be always up.

This works on Proxmox 7.1-10 aswell. Why do they make it so god damn difficult anyways, for everyone doing this if you're like me and you're risking it all. Use cp to make backups from the files you delete just in case it shits on itself.

[devdzpro]

what about vm in the node steel work or not

[Trpke]

Explaining something, that is like really understandable, too much of repeating the same sentence
