rename node

[cazz]

Hi
I have follow this guide
https://pve.proxmox.com/wiki/Renaming_a_PVE_node

and I wonder do I need to restart the Proxmox server?
I can't see any change and now I can't access any servers console.
I get "Error 500: failed to get address info for: pve: Name or service not known"

Hello

and I wonder do I need to restart the Proxmox server?

Yes.

I can't see any change and now I can't access any servers console.

Can you provide us with the output of:

/etc/hostname
/etc/hosts

 

[cazz]

/etc/hostname

prox1

/etc/hostname

'127.0.0.1 localhost.localdomain localhost
192.168.1.2 prox1.mydomain.nu prox1

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Going to move my server this weekend and that mean that I have to shutdown everything.
So I can see after that if the node have change name.

I did startup my proxmox server but how do I move my VM to the new node?

/UPDATE
Did find that I have to move my conf file to the new node and I do that now

Hi, same issue for me.
Changed the /etc/hosts and /etc/hostname files and rebooted PVE.
New hostname is applied OK but all my VMs are greyed-out (under the previous hostname).
What setting(s) did you alter in the conf file to fix that? Thanks

 

[cazz]

Hmm sorry but I dont remember more then I have write in the update
I did just move my conf files to the new node
I did it from shell.

Here's what I've done to resolve my issue:

# hostname intel-pve
# vi /etc/hosts (reflect your new hostname e.g. intel-pve)
# vi /etc/hostname (reflect your new hostname e.g. intel-pve)
# cp -p /var/lib/rrdcached/db/pve2-node/proxmox /var/lib/rrdcached/db/pve2-node/intel-pve
# cp -p /var/lib/rrdcached/db/pve2-storage/proxmox/* /var/lib/rrdcached/db/pve2-storage/intel-pve
# service pve-cluster stop && pmxcfs --local
# mv /etc/pve/nodes/proxmox/qemu-server/* /etc/pve/nodes/intel-pve/qemu-server
# rm -Rf /etc/pve/nodes/proxmox
# rm -Rf /var/lib/rrdcached/db/pve2-node/proxmox
# rm -Rf /var/lib/rrdcached/db/pve2-storage/proxmox
# reboot

Thank you very much! Your answer helped a lot.
Why hasn't this information been added to the official proxmox documentation yet? There is not a word about this on the page https://pve.proxmox.com/wiki/Renaming_a_PVE_node

I agree the Wiki documentation should have some examples in a code block.

I think I just screwed up. I tried to change the hostname/node name. First did the wiki steps...doesn't allow me to load the web interface. Then I tried the steps above, still doesn't work.

Now I just want to go back to the original. I still have access to SSH and the physical terminal.

Is there a way to recovery the web interface?

# cp -p /var/lib/rrdcached/db/pve2-node/proxmox /var/lib/rrdcached/db/pve2-node/intel-pve
# cp -p /var/lib/rrdcached/db/pve2-storage/proxmox/* /var/lib/rrdcached/db/pve2-storage/intel-pve
# service pve-cluster stop && pmxcfs --local
# mv /etc/pve/nodes/proxmox/qemu-server/* /etc/pve/nodes/intel-pve/qemu-server

# rm -Rf /var/lib/rrdcached/db/pve2-node/proxmox
# rm -Rf /var/lib/rrdcached/db/pve2-storage/proxmox
# reboot

I just want to say my thanks to you too!
The official Wiki completely fails to mention that renaming the Node with active VMs will break your setup... This should honestly be added and I hope the Admins here can bring that change in somewhere. @Moayad

Thank you! I had to also modify content of
/etc/pve/storage.cfg

        content iso,vztmpl,backup
        shared 0
