All the partitions will still exist, so ad0s1a will become ada0s1a and ad4s1a will become ada1s1a. There is a chance that ad0 will become ada1 and ad4 will become ada1 instead. That depends on how your PCI devices are laid out on the PCI bus. I can't answer that without seeing a dmesg though. Do you have mav's latest changes? They should provide aliases for the old names along with printfs to let you know what the new names are for each old disk I think. -- John Baldwin
