Hi All,
I'm trying to setup a test CouchDB cluster across two machines and struggling to get it working and understanding how the node names work. I'm am able to sucessfully call the _nodes endpoint on one of the machines to add the other but I don't think this is doing the right thing since the cluster_nodes array is updated with the new node but the all_nodes array isn't... Where I think I'm going wrong is setting the node names in the the vm.args files and then specifying the correct node name when trying to add the second machine to the first instance. In my case the machines have host names but neither machine can contact the other via this and can only contact the other via IP address. Ideally I'd only like the machines to connect to each other via IP and not host name as this will make maintenance of the cluster much simpler going forward. In this situation I'm not sure of: * Whether I should be setting -sname or -name in vm.args. When using -name, my testing suggests I should use a name of the form "node1" with no @ symbol. Is this right? * For -name I'm not sure whether it's supposed to be "node1@<the ip address>" or "node1@<the hostname>" or "node1@localhost"? * Once I've set the name I'm not sure how to refer to the other node when trying to add it via curl. If I've used -sname should I just use the short name (e.g. "node2") or "node2@<the ip address>"? If -name is used in vm.args is the correct thing to do to use "node2@<the ip address>"? I don't believe I have a connectivity issue between the nodes but the ports that are open between them are 4369, 5984, 5986, 9100-9200 (all TCP) and all UDP. When trying to remove the node, to try further variants to see if they work, I get an error about a document conflict. I suspect this is because CouchDB is getting into a strange state but this makes a trial and error process of figuring out how the node names work as difficult to say the least. Any help would be appreciated - Thanks! Simon Disclaimer: This message contains confidential information and is intended only for the individual(s) named.
