Hi, I searched the pacemaker mailing list archive but unable to find the information (The closest thread that I can find is http://www.mail-archive.com/pacemaker@oss.clusterlabs.org/msg08643.html)
I have setup a Linux cluster with Corosync/Pacemaker, and the two cluster nodes are within the same subnet sharing a virtual IP. For machines within the same subnet, they can ping the virtual IP "135.121.192.104" successfully. However, if I tried to ping the virtual IP "135.121.192.104" from the machine from a different subnet, then it does not respond to my ping. The other machines resides on the subnet "135.121.196.x". Note that I was able to ping the individual nodes IP addresses from the different subnet successfully, it is just the virtual IP does not work. On my machines, I have the following subnet mask in my ifcfg-eth0 file: NETMASK=255.255.254.0 and below is my output for the crm configure show: [root@h-008 crm]# crm configure show node h-008 \ attributes standby="off" node h-009 \ attributes standby="off" primitive SampleClusterIP ocf:heartbeat:IPaddr2 \ params ip="135.121.192.104" cidr_netmask="23" \ op monitor interval="30s" clusterip_hash="sourceip" clone SampleClusterIP2 SampleClusterIP \ meta globally-unique="true" clone-node-max="2" property $id="cib-bootstrap-options" \ dc-version="1.0.11-1554a83db0d3c3e546cfd3aaff6af1184f79ee87" \ cluster-infrastructure="openais" \ expected-quorum-votes="2" \ no-quorum-policy="ignore" \ stonith-enabled="false" rsc_defaults $id="rsc-options" \ resource-stickiness="100" and the output of the crm_mon status: [root@h-009 crm]# crm_mon status --one-shot non-option ARGV-elements: status ============ Last updated: Thu Jun 23 08:12:21 2011 Stack: openais Current DC: h-008 - partition with quorum Version: 1.0.11-1554a83db0d3c3e546cfd3aaff6af1184f79ee87 2 Nodes configured, 2 expected votes 1 Resources configured. ============ Online: [ h-008 h-009 ] Clone Set: SampleClusterIP2 (unique) SampleClusterIP:0 (ocf::heartbeat:IPaddr2): Started h-008 SampleClusterIP:1 (ocf::heartbeat:IPaddr2): Started h-009 I am new to the Linux HA cluster setup, and unable to find out the root cause for the issue. Is there any configuration I can check to diagnose this problem?
