Synopsis: Filesystem corruption with ata(4) software-raid on HPT370.

State-Changed-From-To: open->closed
State-Changed-By: sos
State-Changed-When: Mon May 5 02:48:15 PDT 2003
State-Changed-Why: 
You cannot just dd one disk to another and then create a RAID ontop of that.

You need to create the RAID *before* you create (disklabel newfs) your filesystems.

What you encounter is problems because you fool the system into using a
mirror where the two parts are almost but not entirely identical.
