Migrating VM "no such cluster node"

[dignus]

Hi,

I just added the 5th node to my proxmox cluster. All seems well. It's shown as online in the interface, I can interact with it from the interface (create VM's).

However .. I'm not able to migrate VM's onto it. It tells me "no such cluster" node after picking it from the drop down menu.

Any clues? Am I missing something?

Hi,

are you on all nodes on the same PVE versions?
pveversion -v

 

[dignus]

Yes, all nodes are the same, running the very latest version.

I've been able to isolate the problem further. I can't seem to migrete from one specific node to this new node. The difference between this node and other nodes is that in "pvecm nodes" I see an IP for the node I can't migrate to. On the other nodes I see a hostname.

 

[wolfgang]

can you send the corosync conf it is located in /etc/pve/corosync.conf

I added a few more nodes today. On one of the nodes I'm seeing the same issue: can't migrate from one specific node to another. Also in this one the output of pvecm nodes contains an IP instead of a hostname.

How to fix this? Put hostname for each machine in hosts file?

Did you ever find a solution to this? I am seeing something similar, where a newly added host node can't receive migrated VMs, even though the cluster seems to be in sync when checked from the console. The new node doesn't show up in the web GUI of every other node, however, only some of them... is that what you saw as well?
