Deleted Default Linux Bridge to a Node in Cluster

[aschmitt]

I Deleted the Default Linux Bridge to a Node in my 3-node cluster, and when I went to switch it out with an OVS Bridge, Cluster will not connect to node.

I ended up gaining SSH access, and I copied the /etc/network/interfaces.new from another SSH session to another node, and changed the IP addresses accordingly. Rebooted the Node, and now I can't even SSH. I do have physical access to the Node for the next hour or so.

Help?

Cluster communication takes place via the network where the address of pvelocalhost /etc/hosts belongs to (regardless which interface has it assigned currently)

Let's assume your (new) IP is 192.168.1.1 and your hostname is myhost1 the respective line has to look like:

192.168.1.1 myhost.mydomain.com myhost pvelocalhost

Thank you for your reply!

I ended up rebuilding from scratch the entire cluster. However, for curiosity's sake, does the WebGui also go through that IP address or is there another line there?

I haven't taken a look at the hosts file yet.
I guess I should do that.

Do you mean "which IP is WebGui service listening to?" If so: for connecting to WebGui you can use any address defined in the host.
