at the moment I'm doing some researching on Virtualization on Linux. My target scenarion would be a 2 Node "Cluster" with replicated storage over IP. (a little Like Windows HCI)

I already took a look at Open-Stacks but thats a little oversized and putting it all together feels like a 1000 Parts Puzzle :)

So going back to the Basics looking at KVM i saw that you can do Live Migration If you have a shared storage.

So now to the question: Is there an easy way to implement a Storage Replication for that Usecase in Linux?

I would be very tankful if someone can Point me in the right direction.

You can easily do this with GlusterFS:

So basically, you'll use the bricks with GlusterFS and then install KVM on top (guests disks) so you can do live migration between the two nodes seamlessly.
