I thought about it, but that's not very efficient then: - I have to create a logical volume on both sides - I have to create a DRBD device for each such logical volumes With two or three logical volumes it may work, but with more then 10, it becomes to be a bit of administrative burden. As it is to be a temporary solution, I'd rather avoid it. But as I see in documentation, it won't work the way I want (which is: two DRBD machines sync only areas that changed whenever they were disconnected). -- Tomasz Chmielewski http://wpkg.org
