Hi, For testing purposes, I have set-up 4 virtual machines, runing Ubuntu 11.4 and Gluster 3.2.3-1 from the Debian packages (glusterfs_3.2.3-1_amd64_with_rdma.deb). I start the CLI from one of the servers and I can peer probe one other server, but trying to add a 3r server takes long time to respond and does not return a success message: $ sudo gluster gluster> peer probe gluster1.desktops.cs.ait.ac.th Probe successful gluster> peer probe gluster3.desktops.cs.ait.ac.th ... takes two minutes to reply... gluster> peer status Number of Peers: 2 Hostname: gluster1.desktops.cs.ait.ac.th Uuid: 7996c3aa-bf0c-4d17-8751-6d97d6671d23 State: Peer in Cluster (Connected) Hostname: gluster3.desktops.cs.ait.ac.th Uuid: 00000000-0000-0000-0000-000000000000 State: Establishing Connection (Connected) gluster> quit $ uname -a Linux gluster4 2.6.38-8-server #42-Ubuntu SMP Mon Apr 11 03:49:04 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux $ This happens the exact same way when I try from any server, adding any other server. My 4 VM are clones, so I may have missed some dependencies. There is no firewall running. Help will be greately appreciated. TIA Olivier
