After a couple years I'm back looking at glusterfs again for a new project. I downloaded, compiled and installed glusterfs 3.1.2 from tarball. I did this on 2 ec2 servers. Everything compiled and installed fine. I started the daemon on both servers and then on the primary server I tried to do a probe: sudo gluster peer probe 10.XXX.58.95 (just hangs) ^C sudo gluster peer probe status Number of Peers: 1 Hostname: 10.XXX.58.95 Uuid: 00000000-0000-0000-0000-000000000000 State: Establishing Connection (Disconnected) So I detached the peer and tried again. Same result. The 2 servers are in the same security group. I can ping between the 2 servers on the internal IP's without a problem. What am I missing here? Regards, Gerry
