Hi, I'm configuring my first cluster following the documentation. I have a dedicated nic for corosync on 192.168.9.0/24 network. On the first node (192.168.9.106) I run 'pvecm create pve-cluster-01' and no errors were reported. On the second node I run Code: pvecm add 192.168.9.106 --ring0_addr 192.168.9.78 ... Request addition of this node 500 cluster not ready - no quorum? Then Code: pvecm status Corosync config '/etc/pve/corosync.conf' does not exist - is this node part of a cluster? Cannot initialize CMAP service pvecm nodes Corosync config '/etc/pve/corosync.conf' does not exist - is this node part of a cluster? Cannot initialize CMAP service On the first node Code: pvecm status Cannot initialize CMAP service I guess the first step went wrong but i got no errors. PS: the two dedicated nic are connected to a TP-Link TL-SG105E switch. I enabled IGMP snooping on it. Any suggestion? Any log I can look at? Looking at the man page, I think I should create the cluster on the first node by the rin0_addr option in first place. Otherwise it would bind to another address. Code: pvecm create <clustername> [OPTIONS] .... --ring0_addr <string> (default = Hostname of the node) Hostname (or IP) of the corosync ring0 address of this node.
