[SOLVED] Removing a node from a cluster of 2 nodes

[ykrons]

Hello,

I have a proxmox VE 7.1-6 cluster composed of two nodes and I would like to remove one.
I have tried to follow steps : https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_remove_a_cluster_node
but I'm not able to delete the node because "pvecm delnode <node name>" returns error "cluster not ready - no quorum?"

pvecm status gives me:

Votequorum information
----------------------
Expected votes: 2
Highest expected: 2
Total votes: 2
Quorum: 2
Flags: Quorate

So I have tried to adjust the expected votes with "pvecm expected 1"
but I get an error

pvecm expected 1
Unable to set expected votes: CS_ERR_INVALID_PARAM

I guess the value is too low (even if help says 1 is valid), because "pvecm expected 2" seems to succeed.

Did someone know, what is the proper way to remove a node in a 2 node cluster?

Setting the expected votes to one would mean that no majority can be found (since there are two active nodes, each with one vote). Hence the CS_ERR_INVALID_PARAM error. To delete a node you will need 50%+1 nodes to vote for removing it. You could try to shut down the node you want to remove, then set pvecm expected 1 and execute the pvecm delnode <node-id> command.

hi,

I have tried to follow steps : https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_remove_a_cluster_node

i think you should rather follow these instructions [0]. make sure you've moved out all your guests from the node to be removed.

Ok thanks a lot. I will give it a try.

Hi,

I got an error message, but it seems the node has been removed anyway.

$ pvecm delnode XXXX
Could not kill node (error = CS_ERR_NOT_EXIST)
Killing node 1

Thanks!
