Comunication Failure After Change Cluster Network IPs

[Maël Jeuffrard]

Hi,

First: I'am so sorry, my english is too bad and it's not easy for me to describe my problem.

I've 1 cluster Proxmox-ve with 4 nodes.
I've dedicated network for the cluster communication on vmbr0 & Multicast is activated.
Recently i've change the IPs of vmbr0 on all nodes. I also edit hosts file and corosync.conf.
Quorum is OK and migrations of VMs works fine.
The problem is, i can't see some options of one vm if she on another node.
It works fine only if i'am connect to the node4. If i'am connect with another (Node[1-3] i view only options of them nodes.

The page going to the timeout with "proxmox communication failure (0)"

Thanks a lot for your help, and of course if you need more information, i will send them.

Regards,
Maël

cat /etc/hosts
cat /etc/hostname
cat /etc/network/interfaces
cat /etc/pve/corosync.conf
cat /etc/pve/.members

Your config looks ok.
Try to restart the following services on all nodes.

systemctl restart corosync.service
systemctl restart pve-cluster.service
systemctl restart pvedaemon.service
systemctl restart pveproxy.service
systemctl restart pvestatd.service

 

[Maël Jeuffrard]

OK,
I've a Vms in production.
they will be stopped?

 

[wolfgang]

No this are only the management tools.
In worse case you can't manage them.
If you have HA enabled please deactivate it.

 

[Maël Jeuffrard]

All services are restarted successfully.
But not solved problem :-(

Thanks again
