You must be referring to that one sentence on one page in one manual that says you must start the raw partition on cylinder 1, not 0.

Pay close attention to this warning. If you choose not to, then pay close attention to the part that says to do a full export before mucking with the file systems.

I switched our system to raw FS last night. I screwed it up so bad that at 4am I slapped in the Oracle CD-ROM to do a complete reinstall. If you start a raw partition at cyl 0, then everything looks great, until you reboot. Oracle flat refuses to come up, the disk labels are gone, and the partition tables are scrambled.

No fun.
