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 {
name: proxmox-worker3
nodeid: 4
quorum_votes: 1
ring0_addr: 10.40.191.243
}
node {
name: proxmox-worker4
nodeid: 5
quorum_votes: 1
ring0_addr: 10.40.191.244
}
node {
name: proxmox-worker5
nodeid: 6
quorum_votes: 1
ring0_addr: 10.40.191.234
}
}

quorum {
provider: corosync_votequorum
}

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.
