Hi Dan, So I took your advice, and I have added all of the machines- 2 Gluster Storage Machines, and 6 Xen Host Machines to each machines hosts file. Now all machines are pingable by name. I am afraid that did not correct the issue. I have a more basic question. Should both machines be reachable via NFS if they are set to replicate between the two. Because I'm not sure this is as much a Xen issue, more over I am unable to connect to the second machine once I have changed the port number (to meet the Xen requirement) Thoughts?
