how to remove a node?

[Gad]

Hi i wanted to test the ability to have two nodes of proxmox
but now when i turn off , one node , i am getting erros on the other node

how can i tell proxmox that i dont want to have two nodes?

i am unable to reboot or do anything if node two is not online
i have seen the below post but it talks about how to remove all VMs from cluster
but i want to keep my orginal node , and not delete
https://forum.proxmox.com/threads/removing-deleting-a-created-cluster.18887/

please help

Hi,
take a look here.

https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node

 

[Gad]

thank you i did not see this...
so i need only to power off the node
then from shell of node1 remove node2
node1# pvecm delnode node2

 

[oguz]

yes. but be careful about putting node2 back online. you should wipe it first.

 

[Gad]

will do!

Hi i have two issues, please help
1. when trying to remove i am getting IPs and not names
error :400 Parameter verification failed. when i put the ip

2. i did as guide said

pvecm nodes
shutdown (node 2)
pvecm delnode node2

i am getting the no qurm 500 error when node2 is powered off?
do i need to keep it up when i try to remove it? wiki says it should be down when i do delete

Thanks!

Gad, try `pvecm expected 1`, then run the delnode command again.
