Guys,
I am looking for information of how to deal with a KVM three node cluster
with DRBD

I have a "baby machine" ubuntu 11.10 pacemaker/drbd cluster with two nodes,
local disks with drbd setup in between. This is working flawless.

My challenge now is that I want to add a third node with the same setup.
How do I handle drbd in this setup? I'd like to have all nodes active, to
be able to migrate resources, mainly kvm virtual guests, around the cluster
as I see fit. I'd also like pacemaker to be able to dynamically handle the
load.

I've been surfing' around for a while... Either I am not able to find the
right information, or it is so obvious how to handle this so I am missing
the point somewhere. Or, in worst case, this is not possible and I need to
enter another route to make this work as I want.

Any ideas?

Thanks a lot in advance for your patience with me
