raid 0 with 3 drives doesn't work

[ben morse <ben@xxxxxxxxxxx>]

I already emaild this to Heinz, but I can't get raid 0 to work on my 
machine with 3 devices.  It works just fine with 2, but not with 3.   
When I setup 3 devices, the stride gets read totally wrong, and I get 
the error:
ERROR: dos: reading /dev/mapper/nvidia_bhddebdb[Device or resource busy]

So I don't know, it seems like this would be a simple fix, but I don't 
much about C, so just letting you know.  Thanks for the awesome program.
