> raw FS

There really isn't anything like that. Every logical volume starts as a raw device. You might use it as a swap area, or run newfs to create a filesystem in it, or it might be used by a database such as Sybase, Informix or Oracle as a raw partition. So when you reboot, you MUST shutdown any processes that use this area. If you randomly kill any of those processes, especially kill -9, you will likely corrupt the raw volume.

And you'll need a good raw volume backup program so you can restore the volume when it is corrupted or destroyed.
