Hi all , I am using the 2 node cluster with drbd. For sending the cluster packets & drbd packet I have connected the 3 cross cable between 2 server. The IP and config is as follows :-- service mailbox1 mailbox2 Interface --------------------------------------------------------------------------- 1) drbd res0 10.10.10.10/16 10.10.10.20/16 eth1 2) drbd res1 10.10.10.30/16 10.10.10.40/16 eth2 3) Cluster Packet 10.10.20.1/16 10.10.20.1/16 eth5 cat /etc/hosts 10.10.20.1 mailbox1 10.10.20.2 mailbox2 ################# part of cluster.conf ######################## <clusternode name="mailbox1" nodeid="1" votes="1"> <multicast addr="224.0.0.1" interface="eth5"/> <clusternode name="mailbox2" nodeid="2" votes="1"> <multicast addr="224.0.0.1" interface="eth5"/> ################# part of cluster.conf ######################## Cluster log :-- ---------------- Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] CLM CONFIGURATION CHANGE Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] New Configuration: Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] r(0) ip(10.10.10.20) Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] Members Left: Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] Members Joined: Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] CLM CONFIGURATION CHANGE Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] New Configuration: Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] r(0) ip(10.10.10.10) Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] r(0) ip(10.10.10.20) Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] Members Left: Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] Members Joined: Apr 1 00:45:39 mailbox2 openais[4228]: [CLM ] r(0) ip(10.10.10.10) Apr 1 00:45:39 mailbox2 openais[4228]: [SYNC ] This node is within the primary component and will provide service.
