Joining a cluster fails

Hi all

I have two fresh machines installed with the latest Proxmox and updated.

pve1 - 192.168.1.10
pve2 - 192.168.1.11

On pve1 I used the GUI to create a cluster. I then moved to pve2 and initially used the GUI to add pve2 to the cluster. This failed so I tried the command line and received the same error message. The thing is, the error doesn't make sense

root@pve2:/etc/network# pvecm add pve2.23wwc.io
detected the following error(s):
* local node address: cannot use IP '192.168.6.2', it must be configured exactly once on local node!

Check if node may join a cluster failed!

My network is 192.168.0.0/21 so 192.168.6.2 is a valid address but I have no idea why it's appearing here unless pve2 picked up that address from DHCP during the install - I set the IPs manually during the install process.

Either way, I can't get this message to go away. I've even tried greping the entire hard disk for 192.168.6.2 and found nothing. Googling for "local node address: cannot use IP " and/or "it must be configured exactly once on local node!" finds one person who experienced this error but not for same reason and the actual source code the generates this message but I didn't find a solution.

Can anyone help me make this message go away or do I need to do a reinstall?

Thanks

Steve
 
Hi,
