Re: Physical shutdown of one node causes both node to crash in active/passive configuration of 2 node RHEL cluster

Hi,

Is this two connected crossover cable with bonding ? Do you have switch in the middle ?

Note: Red Hat does not support use of a crossover cable for cluster communication.

Hi,

I have setup a 2 node cluster using RHEL 6.5 .

The cluster .conf looks like this 

 

<?xml version="1.0"?>
<cluster config_version="7" name="oracleha">
        <cman expected_votes="1" two_node="1"/>
        <fencedevices>
           <fencedevice agent= "fence_ipmilan" ipaddr="10.10.63.93" login="ADMIN" name="inspuripmi"  passwd="XXXXX/>
           <fencedevice agent = "fence_ilo2" ipaddr="10.10.63.92" login="test" name="hpipmi"  passwd="XXXXX"/>
          </fencedevices>
      <fence_daemon post_fail_delay="0" post_join_delay="60"/>
        <clusternodes>
           <clusternode name= "192.168.10.10"  nodeid="1" >
           <fence>
               <method name  = "1">
                 <device lanplus = "" name="inspuripmi"  action ="">
                 </method>
            </fence>
           </clusternode>
            <clusternode name = "192.168.10.11" nodeid="2">
                 <fence>
                 <method name = "1">
                  <device lanplus = "" name="hpipmi" action ="">
                  </method>
               </fence>
            </clusternode>
         </clusternodes>


        <rm>

          <failoverdomains/>
        <resources/>
        <service autostart="1" exclusive="0" name="IP" recovery="relocate">
                <ip address="10.10.5.23" monitor_link="on" sleeptime="10"/>
        </service>
</rm>

</cluster>


The network is as follows:

1)Heartbeat (Bonding) between node 1 and node 2  using ethernet cables 

The ip addresses are 192.168.10.11 and 192.168.10.10 for node 1 and node 2.

2) IPMI.  This is used for fencing and addresses  are 10.10.63.93 and 10.10.63.92

3) External ethernet connected to 10.10.5.x network.

If i do fence_node <ipaddress>, then fencing works,
However if i physically shutdown active node, the passive node also shutdowns. Even if i do ifdown bond0 (on active node), both node shutdown and have to be physically rebooted.

Any thing i am doing wrong ?
