May I ask you some question

[Huang QingHua]

Dear:      May I ask you some question?      1.I try to make a  filesystem. But if my block size have to be 1M ,then what should I do ? Or is it possible?      2.When to reading  a  hardware page from disk and when to read a block from disk? Is there a order between them? just for a easy example. When I want to read a big file ,It seems to use getblk function (from my studying source code...) ,Is it right? When is reading a page called.      Would you help me again?      Thank you very much! best wishes!    yours Huang QingHua         [EMAIL PROTECTED]
