Linux filesystems can't have block sizes greater than the machine's page size. For x86 and x86_64 that's 4096 bytes. I've seen 16k pages on a IA64 box, so you can go larger there.
I remember some threads on LKML about larger page sizes on x86.
Not sure on the current status, but you'll want to look into "page cluster".
There are huge pages, meaning you can configure some subset of the pages in a system to be a lot bigger than default (4MB on x86 boxes). I don't think that helps filesystem block sizes any. Or were you thinking of something else?
Yes, I'm thinking of something else.
