Thanks Pavlos! So it confirms what I thought, it's not possible with pacemaker 0.6. That's no good news, as I'm not allowed to install anything in this server that isn't coming from the official CentOS repositories...
Let's say I don't mind whether the resource comes back to it's original node. Imagine, that apache fails on node1, then node2 starts apache. Now imagine that after a few days, apache also fails on node2. In this case, node1 will failover. The thing is that node1 never tries to start Apache. I suppose this is because of the fail-count? Is there a way to circumvent this? 2010/12/1 Pavlos Parissis <pavlos.paris...@gmail.com> > On 1 December 2010 14:53, Marc Wilmots <desj...@gmail.com> wrote: > > Hi list, > > > > I'm kinda new to Pacemaker and have some questions I hope some of you > could > > help me with. > > > > First of all, I'm using Heartbeat v2.1.3 with CRM still integrated.
