Rhesa, the problem is datastore 0, it's the system datastore. If you move it to the local nodes, it will not be shared and synchronized across the nodes, therefore you will lose many benefits like live-migration and instant persintant image VM deployment.
Why is it that you want to move datastore 0 to the frontend + nodes?
