Yes, probably you're right as the modification date points to the time period when I turned on the LAGG As I understand, on 10.x it's fixed and having more queues results in better performance? As far as I will have faster transfer between storage1 and storage2, I'd plan to upgrade 9.x to 10.x Cheers, Marek
