[SOLVED] Changing corosync address

[etfz]

Hi,

I'm in the process of setting up my cluster and have made a bunch of networking changes. I've just changed the corosync addresses by editing corosync.conf. pvecm status shows me that the new addresses are in use. When I removed the bridge using the old address from one of the nodes, however, I was no longer able to access that node via the web interface. What do I need to do in order to rectify this?

I still don't really understand which network is used for reaching all nodes via the web UI. I greped /etc for the old address, and found that it's still present in /etc/pve/.members and /etc/hosts, so I'm guessing that's the issue, but I would like to know the proper way of dealing with this.

Corosync is unrelated to the PVE web GUI, though of course necessary for a cluster. See if this thread helps: https://forum.proxmox.com/threads/change-cluster-nodes-ip-addresses.33406/post-163795.

Thanks. I updated the hosts files, and it works now. So, the web UI simply uses hostnames to reach other cluster nodes. /etc/pve/.members seems to have been automatically updated with the same addresses.
