Hi all, I am trying to setup 3-node cluster but constantly one of the nodes fail to sync with master. Here is what I do: 1. I create 3 VMs with CentOS 7.2 minimal (`3.10.0-327.el7.x86_64`) 2. I install DRBD9 RPMs I have built myself from following tags: drbd: 9.0.9, drbd-utils: 9.1.0, drbdmanage: 0.99.10 3. I setup SSH passwordless authentication between all 3 nodes 4. I setup hostname and add all hostnames to /etc/hosts on each node 5. On master, I run `drbdmanage init [MASTER_IP]` 6. On each slave I run `drbdmanage add-node [SLAVE_HOSTNAME] [SLAVE_IP]` ...and what happens is that first slave synchronizes with master properly but the second one hangs in "Connecting" state and is marked on master as "StandAlone": .drbdctrl role:Primary volume:0 disk:UpToDate volume:1 disk:UpToDate node-10-9-4-137 role:Secondary volume:0 peer-disk:UpToDate volume:1 peer-disk:UpToDate node-10-9-4-192 connection:StandAlone According to user's guide, this should work out-of-the-box but somehow it doesn't. Am I missing something? Should I do some pre-setup that's not mentioned in the user's guide? I've collected output from drbdadm, drbdsetup, dbus-monitor --system and syslog, if anyone would be willing to help me with this I have put the logs on github: - master: https://github.com/localghost/issues/tree/master/drbd/node_does_not_sync/before_adjust/10.9.4.119/logs - slaves: * successful: https://github.com/localghost/issues/tree/master/drbd/node_does_not_sync/before_adjust/10.9.4.137/logs * failing: https://github.com/localghost/issues/tree/master/drbd/node_does_not_sync/before_adjust/10.9.4.192/logs Thanks, Zbigniew Kostrzewa
