Heartbeat with 3 nodes configuration

[playmokill]

Hi all.

I trying to configure a cluster with 3 nodes. But the documentation in the HA project site (HomePage: Linux HA) is very confused to me.

I need help to perform this configuration.

How i made to proceed to get one Cluster with 3 nodes in the same resource.

Following are my settings:

root@db1:/# cat /etc/ha.d/ha.cf
logfacility local0
logfile /var/log/ha-log
debugfile /var/log/ha-debug
use_logd on
udpport 694
keepalive 1 # 1 second
deadtime 10
initdead 80
bcast eth0
#serial /dev/ttyS0 #if you use serial
#baud 19200 #if you use serial
node db1
node db2
node db3
crm yes
auto_failback yes

root@db1:/# cat /etc/ha.d/authkeys
auth 1
1 sha1 db

root@db1:/# cat /var/lib/heartbeat/crm/cib.xml
<cib>
    <configuration>
        <crm_config>
            <nvpair id="transition_idle_timeout" name="transition_idle_timeout" value="120s"/>
            <nvpair id="symmetric_cluster" name="symmetric_cluster" value="true"/>
            <nvpair id="no_quorum_policy" name="no_quorum_policy" value="stop"/>
        </crm_config>
        <nodes>
            <node id="f67904e0-4dfc-4db1-83a2-e930fc1d20f4" uname="db1" type="member"/>
            <node id="e9bdfde9-01b0-421f-acd8-8a65a53e775f" uname="db2" type="member"/>
            <node id="5d9a8c11-8684-43ea-9180-5e221530c193" uname="db3" type="member"/>
        </nodes>
        <resources>
            <group id="db_group">
                <primitive id="db_ip" class="ocf" type="IPaddr" provider="heartbeat">
                    <instance_attributes>
                        <attributes>
                            <nvpair name="ip" value="192.168.10.45"/>
                        </attributes>
                    </instance_attributes>
                </primitive>
            </group>
        </resources>
        <constraints>
            <rsc_location id="location_apache_group" rsc="apache_group">
                <rule id="prefered_location_apache" score="100">
                    <expression attribute="#uname" operation="eq" value="db1"/>
                </rule>
                <rule id="prefered_location_apache" score="50">
                    <expression attribute="#uname" operation="eq" value="db2"/>
                </rule>
            </rsc_location>
        </constraints>
    </configuration>
    <status/>
</cib>

These configurations is same in the 3 nodes.

I use webmin to setup heartbeat
7.7.Â* Detailed Instructions on Heartbeat Configuration — Cendio ThinLinc

helps a little bit

The Webmin only suport Heartbeat without CRM, like Heartbeat V1.

Heartbeat V1 suport only 2 nodes. I need 3 nodes.

Tnx.
