Just added a new machine to our cluster, but it's not showing up in the web gui for all nodes. If I go to say node C or D, all 6 show up, but if I go to node A, only A-E show up and no F. I ssh'd into some of the nodes, and noticed their /etc/hosts doesn't have all the nodes there either. What can I do to fix? Long story: I added 3 new nodes to my cluster as an upgrade, and will be killing off the 3 oldest soon. But in the meantime I have all 6 running, but not all 6 show up to eachother.
