I have two nodes running heartbeat 3.0.5 and pacemaker 1.1.6 (both from the
linux-ha lucid ppa). They are running 11 groups each comprising an
ocf:heartbeat:IPaddr2, an ocf:heartbeat:SendArp and an ocf:heartbeat:MailTo.
There is also a mailto resource configured for the overall cluster.
/unmove that doesn't apply location rules, but just tells the
resource to move?

So if all that's true, why is that resource group still on the original node?

As Dmitri said, heartbeat has other strengths, especially when it comes to more

. One critical aspect of an HA system is that it should be really easy
to deal with when things go wrong; I'd put xtrabackup in this category - it's
great (though I hope you have automated tests for your restores as it went
through a patch late last year when they were broken!).
