Hello together I have installed a openfiler-configuration with 2 nodes (same hw) with corosync, pacemaker and drbd using the following howto: http://www.howtoforge.com/openfiler-2.99-active-passive-with-corosync-pacemaker-and-drbd. On page two in section 4.1 i checked the corosync state with the command Code: crm_mon --one-shot -V and i get always a one-node configuration: Code: ============ Last updated: Wed Aug 31 10:14:19 2011 Stack: openais Current DC: node1 - partition WITHOUT quorum Version: 1.1.2-c6b59218ee949eebff30e837ff6f3824ed0ab86b 1 Nodes configured, 2 expected votes 0 Resources configured. ============ Online: [ node1 ] why is the second node node2 not visible?

is the interface { } part in the config on both servers exactly the same? double check please. If you have a different port or mcast address, the nodes won't see each other.
We could found the solution, its very interesting. The used multicast adress was blocked by the cisco switch, we used another well known mcast-adress and now both nodes are visible
