Comment 7 for bug 1424060

I agree that just checking for running OSD processes is not ideal. What would you suggest we check for? Is there a way we can check that a particular node has data that needs to be migrated? The idea is to not let the user delete nodes if it could potentially result in data loss, not to actually remove the OSDs from the cluster and wait for rebalancing to finish (they will have to do this work manually before Fuel will allow them to remove the node). That is a worthwhile feature to have in Fuel but it would require a blueprint.
