Problem adding a new node to cluster

[apanescu]

Hello,

I have a cluster of 6 nodes in my proxmox environment and I want to add 3 more. The problem is that I am getting the following error:

"""

Establishing API connection with host '10.40.191.240'
Login succeeded.
check cluster join API version
Request addition of this node
An error occured on the cluster node: invalid corosync.conf
! node 'proxmox-master' has 'ring0_addr', but there is no interface number 0 configured
! node 'proxmox-worker1' has 'ring0_addr', but there is no interface number 0 configured
! node 'proxmox-worker2' has 'ring0_addr', but there is no interface number 0 configured
! node 'proxmox-worker3' has 'ring0_addr', but there is no interface number 0 configured
! node 'proxmox-worker4' has 'ring0_addr', but there is no interface number 0 configured
! node 'proxmox-worker5' has 'ring0_addr', but there is no interface number 0 configured
TASK ERROR: Cluster join aborted!

"""

I used the GUI procedure and also the CLI procedure and I am getting the same error. Does someone have any clue what might be the issue here?

I also attached a file from the GUI error.

Thanks!
Andrei

I forgot to mention that the version of the Proxmox that I am using is 6.2-6.

Thanks!

here is also the corosync.conf file:

root@proxmox-master:~# cat /etc/pve/corosync.conf
logging {
debug: off
to_syslog: yes
}

nodelist {
node {
name: proxmox-master
nodeid: 1
quorum_votes: 1
ring0_addr: 10.40.191.240
}
node {
name: proxmox-worker1
nodeid: 2
quorum_votes: 1
ring0_addr: 10.40.191.241
}
node {
name: proxmox-worker2
nodeid: 3
quorum_votes: 1
ring0_addr: 10.40.191.242
}
node {

nodeid: 4

ring0_addr: 10.40.191.243
}
node {

nodeid: 5

}
node {

}
}

quorum {

totem {
cluster_name: XXXXXXXXXX
config_version: 6
interface {
bindnetaddr: 10.40.191.240
}
ip_version: ipv4-6
secauth: on
version: 2
}

I managed to find the issue. I had to reconfigure the/etc/pve/corosync.conf and change:

interface {
bindnetaddr: 10.40.191.240
}

to

interface {
linknumber: 0
}

So the problem is solved. I think the corosync updated since I installed the cluster for the first time. I hope it helps in case someone else gets into the same problem.

Do you have more than one node that is named: pve?
If yes, use different names for each node.

i found the only other refference to this issue "Cluster Join Failed" on the germal national support section of proxmox that mentioned this might be the case

For anyone else with this issue - making sure your nodes are not named the same was the solution. Hopefully the vague error can be rectified. There is documentation on changing your node name from proxmox here so it would be good to let us know a little more about why adding something to the cluster has failed
