doesn't seem to work. i can still see the node in the UI after following the 'Separate a Node Without Reinstalling'.

Hi,

the node should be inactive now. If it is, you also need to remove the directory /etc/pve/nodes/<nodename>, but I'd first check that there is no configuration you still need in there.

You should do a lot of the removal from the master node.

The node you want to remove should be powered down after you run pvecm delnode Node_Name from the master
pvecm nodes

mv /etc/pve/nodes/node_name /boot

I think you can run the remove node from the node itself also (but I could be wrong).

Here is a real good article to get you there:

I hope this helps,

It should be powered down before, as the documentation mentions:

At this point, you must power off hp4 and ensure that it will not power on again (in the network) with its current configuration.

mv /etc/pve/nodes/node_name /boot

Why would you move it to /boot?

No, it needs to happen from a different node.

So I have done this few times and if you do it the way the link says to, then it works fine. However if you do not move the /etc/pve/nodes/node_name to somewhere else it will stay in the web gui list of nodes with a red x on it and not remove completely. At least that has been my experience. I am not here to dispute anyone I am just trying to help is all.

Thanks,

Yes, you need to (re)move the directory. But I'm wondering why you move it to /boot, because that's usually not the best place to move unrelated things to

To be honest that's the way I was taught how to do it. By the way /boot was a typo I apologize.
