Hi. I followed the guide https://pve.proxmox.com/wiki/Renaming_a_PVE_node, and renamed my main node, and also my cluster name. When trying to move a vm back to the newly named node, I get the error

Code:
2023-09-04 21:09:39 # /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=ravenclaw' root@10.60.1.136 /bin/true
2023-09-04 21:09:39 Host key verification failed.
2023-09-04 21:09:39 ERROR: migration aborted (duration 00:00:00): Can't connect to destination address using public key
TASK ERROR: migration aborted

and I only have the option for an offline move, but the node has its green dot next to it.

Thanks for any help in advance!
 
You will probably need to remove the renamed host from the /root/.ssh/known_hosts file:

use the following command to remove the old hostname AND the IP from the file:

Code:
ssh-keygen -f /root/.ssh/known_hosts -R <host>
 
if your node is in the cluster. use the other ip of that node and then edit /etc/hosts

from 10.60.1.136 to <other ip of that same node>
then restart pve-cluster service pve-cluster restart
