Hi Maarten I hope that someone will give you a smarter answer ... but a simple fix would be to split your mirror package file into several sections where each section corresponds to one physical partition. Set local dir in each section to the corresponding partition, ie ... local_dir=/disk_1/debian-stuff ... local_dir=/disk_2/more-debian-stuff ... local_dir=/disk_3/even-more-debian-stuff That way, you see the whole as "one" (thanks to the links), but mirror doesn't get confused.
