I've tried to look at the code many times. But, as a clustered file
system is a complex thing, it gets hard to figure out what it's all
about. I tried to find a "big picture" documentation, at least for
on-disk layout. The only nearest thing i've found is :
http://opengfs.sourceforge.net/docs.php , which is the documentation
written at the time OpenGFS forked from Cistina's code. Although
principles may still be the sames (or not ?), the code has obviously
changed and on-disk layout may not be the same, too.
So, is there some sort of documentation about the principles found in
GFS (not a design doc, i've read
/usr/src/linux/Documentation/stable_api_nonsense.txt) ? This would much
help anybody who wishes to enter the code to do it more efficientely...
Thanks !
