Re: [Linux-cluster] failover not working




You should use Linux H.A. (heartbeat) for failover. the rgmanager very good but not yet. you not must use failover with rgmanager. you can get some problems because of priority and two failover happened some the wrong.

have a nice day..

I have changed it since I posted this. But I though I needed the 2 failover domains? One for each host so if dolphins fails it failsover to patriots and vice versa. Or do I just need one because of the virtual IP?


               <failoverdomains>
                       <failoverdomain name="dolphins-drbd1" ordered="1">
<failoverdomainnode name="dolphins" priority="1"/> <failoverdomainnode name="patriots" priority="2"/>
                       </failoverdomain>
<failoverdomain name="dolphins-drbd2" ordered="1" restricted="0"> <failoverdomainnode name="dolphins" priority="2"/> <failoverdomainnode name="patriots" priority="1"/>
                       </failoverdomain>
               </failoverdomains>
               <resources>
                       <ip address="192.168.5.4" monitor_link="1"/>
               </resources>
<service autostart="1" domain="dolphins-drbd1" name="dolphins-svc-drbd1" recovery="relocate">
                       <ip ref="192.168.5.4"/>
               </service>
<service autostart="1" domain="dolphins-drbd2" name="dolphins-svc-drbd2" recovery="relocate">
                       <ip ref="192.168.5.4"/>
               </service>
       </rm>

That section looks funny. You don't need the two 'failoverdomain's; and you don't need the two services. Does rgmanager even startup? Check /var/log/messages for more info.
