Cluster Join Information has wrong IP address

[DerfM]

Single node, starting up a cluster. The node does have multiple NICs one of which is on the 10. network and the other 4 on the 192 network:


Cluster Join Information:


I'd prefer it be using the 192 network. The 10. network was the first network added to the host.

/etc/hosts:


Corosync.conf:


Do I just need to change the hosts file to reflect the 192 address?

It's using the IP that the hostname of the node resolve to (iow the IP from the hosts file). You can change that, but make sure to do it on all nodes and restart the node aftewards. The IP is just used for the initial 'handshake' on clustering, so not that important. You can configure corosync to use the 192.x.x.x network anyway.

I can also see you have 4 NICs enslaved on vmbr1. Are you sure you want to do this? Usually if you want to use multiple ports as a singular interface you would create a bond [1].

Thanks. I'll give it a go before my next restart. It's just single node right now. It appears corosync is already set up for the 192 network in the conf. Yeah, I'll change the network config. I needed a second NIC but the only one I had on hand was a 4 port so I just threw it in there.
