Hi,
I've got DRBD8 set up and running with Heartbeat + CRM. I've got two
machines, each with a primary partition on and it's secondary on the
alternate machine.

[cib.xml end]
I keep running into problems with the shared IP's not coming back
properly and primary partitions not reverting back when a downed
machine comes back up.
The constraints I got from the linux-ha site but they don't quite do
what I want. I suspect that my scores on the rules and
default-resource-stickiness are the first problem. Is there some good
documentation on how the scoring works? If it's on the linux-ha site
I've missed it.
Is there also some way to get heartbeat to do things on the fly? I've
looked at crm_resource but doesn't that just change the cib.xml file
instead of actually instigating the changes?
Thanks
Guy
