[Pacemaker] getting started

[Frank DiMeo]

Again, thanks.

 

1)       When I restart all the nodes in my cluster, I don't see my previous configuration come back, which is why I was wondering about the persistence.  The was a restart them is by running /etc/init.d/openais stop on both nodes, then running /etc/init.d/openais start on both nodes.  When the DC is finally elected..there are no resources configured...

Thanks for you response,  some comments:

 

1)       So, if we cannot load a persistent configuration after a restart of the all nodes in the cluster, how does one automatically configure an (rebooted) unattended cluster with a known set of resources?  Is it expected that a person will reconfigure a cluster if it were to all nodes in the cluster were to reboot?

You don't have to reload it. The cluster configuration is saved in /var/lib/heartbeat/crm/crm-xx.raw and it survives across reboot. 

	2)       If I'm trying to reduce the DC election time during a complete cluster reboot, so how can I load the dc-deadtime before a DC is elected?

When you configure a cluster initially, just set the dc-deadtime, it will be persistent. 

	 

	3)       Thanks, that's was the problem

	 

	4)       I'm sure your method will work, but the syntax that I used is right out of the documentation for pacemaker (example 6.16 of Pacemaker 1.0, Configuration explained"), so I don't see what's wrong with it.  Regardless, I'll use your method.

Oh, well. That's why we are here to catch a bug!

Thanks
