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.
