Created attachment 589912 [details] engine.log * 3 nodes were added to the gluster cluster using GUI, all nodes are Up. * "gluster peer status" only shows 2 nodes (local + one peer). * When trying to create a volume, the creation fails because one of the hosts isn't recognized as a peer. The problematic host is named "node3" with IP 10.35.97.47.

My mistake, there is no "problematic host". The host 10.35.64.205 shows itself and 10.35.97.162 The host 10.35.97.47 shows itself and 10.35.97.162 The host 10.35.97.162 shows itself and 10.35.97.47
Assigning to Vijay as this looks related to GlusterFS.

How did you install these servers?

How did you install these servers? They are VMs created from a template. This probably has something to do with that. How do I reset a server's UUID?
The UUID for a server is located in /var/lib/glusterd/glusterd.info. I tend to stop the glusterd servive and remove the whole /var/lib/glusterd directory before shutting VMs down and creating the template. When the glusterd service starts the first time, it will populate the directory.
