deleted cluster node still shows up in my gui

[klik333]

restart 'corosync.service' on the node where it's still there

In my case this was a trick. Thanks.

You need to remove the whole directory /etc/pve/nodes/<nodename>

This was driving me crazy!!!!!!!!!
I tried this and nothing changed at first.. Only after systemctl restart corosync.service was I able to get rid of the deleted node
Thank you all

To get the the node to be removed from the GUI I had to delete the node in the nodelist variable inside the /etc/pve/corosync.conf file.

Edit: I believe just restarting corosync would accomplish the same thing.

Hello, I messed up,
I was trying to remove a node from my cluster and accidently
pvecm delnode pm2 before turning of the node.

We'd need a bit more info first:

• How many nodes are and were in your cluster?
• Is this pm2 node the node you WANTED to remove, or was that a mistake-typo too?
• What is the current status of the pm2, is it now already shut down or not?
• What is the results of pvecm status on (all of) your RUNNING node(s)

EDIT: Also for next time, best to create a new topic instead of necro-posting in a 2-year and before that 12-year(!) old topic

Figured this was best place since last post was only 7~8 months ago... non the less,

• How many nodes are and were in your cluster? --- 2 Nodes to begin with
• Is this pm2 node the node you WANTED to remove, or was that a mistake-typo too? -- no this was the one i wanted to removed just didn't shut it down before removing it.
• What is the current status of the pm2, is it now already shut down or not? - yes it was shut down.
• What is the results of pvecm status on (all of) your RUNNING node(s) --- Below but with few changes since last post..

I got some of it fixed, pvecm expected 1 this brought all the vm's back and then rm -rf /etc/pve/nodes/pm2 removed the pm2 directory.

However, im still stuck with vm's not coming back online after i reboot pm1, and i still have pm2 in the GUI, this is where iam stuck for now.

below is output of pvecm status

Since you're going to be running a single node, without a cluster, anyway, probably easier/better to just remove the entire cluster-config from your node 1.
See also: https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node (the section "Separate a Node Without Reinstalling")
The commands you SHOULD have to run, but maybe already partly did (so triple-check things) :

systemctl stop pve-cluster
systemctl stop corosync
pmxcfs -l
rm /etc/pve/corosync.conf
rm -r /etc/corosync/*
killall pmxcfs
systemctl start pve-cluster
rm /var/lib/corosync/*
/sbin/reboot
