Lustre only supports 4096-byte blocksize for ldiskfs, so that makes your study very easy. I suspect that Oracle database uses 8192-byte blocks, but to be honest I don't know anything about it. 

That said, Lustre is probably not very well suited for Oracle databases, but I'd be very happy to see any results you can generate in this configuration. Please post the results to this list. 

Cheers, Andreas
