no, it is because sd0b is swap BY DEFINITION. Do not use the 'a' partition of the first drive for anything but booting. Do not use the 'b' partition of the first drive for anything but swap. Do not use the 'c' partition of any drive. Do not forget there is a strong possibility that some day your first drive may no longer be your first drive, in which case some other drive's 'a' and 'b' will be spoken for. Respect that. If you have a [ws]d0b, it WILL be swap. If you promote sd1b to sd0b, whatever was on 'b' will become swap. IF you want to have swap on RAID, ok...don't create a 'b' partition on your real disks. Create a swap partition on your softraid disk, point to it with fstab. > I figure it's worth a shot on my test system, if it's quicker, I'm not > opposed to the little bit of configuration up front. it's a potential failure point. In a modern computer running typical applications, think of swap as your "oh shit, that wasn't supposed to happen!" recovery zone. In general, if you are optimizing your swap, you are Doing It Wrong. Special cases exist, I'm sure, but it is very much like cleaning the gun and polishing the bullets before putting a hole in your foot. The dirty gun and the tarnished bullet were going to do just fine. Nick.
