Hi The problem is: There is no mechanism to detect block device setup failure Network devices have the same problem, and are fixed with this too. I handling this problem in the way suggested by aliguori: - hotplug scripts write a "hotplug-status" node on store - Xend DevController.createDevice() check verify this node and return success or throw an exception on failure. - If no changes in "hotplug-status" node after DEVICE_CREATE_TIMEOUT seconds Xend throw an exception showing the problem with hotplug scripts. Comments? Regards -- Murillo Fernandes Bernardes
