Hi all,
I want to develop a clustere file system using independent Blade
servers (about 96 in number) running linux. Each blade having 2 or
more SCSI disks attached to it. In order to build our own filesystem I
need to do direct writing/reading in the SCSI disk bypassing all the
kernel level buffering.
Could you please suggest some information as how to go about it.
Best Regards,

A Linux file system doesn't have to use the page cache Linux provides, so
in theory there is no reason it cannot be done. Two obvious examples to
look at are OCFS (oracle's GPL'd cluster fs) and OpenGFS (opengfs.sourceforge.net)
