I know there are more FSs, but I haven't had the time yet to add them to this site.
Some definitions and general technology
To be honest, I don't have any particular reason for writing these pages about the different file systems (and with an emphasis on distributed file systems). I've read loads of articles, webpages and some books about different implementations of file systems, and writing an overview/summaries is the easiest way to remember all the stuff. Hopefully some of you will find these pages helpful, or even useful, and will give you at least some insight in the matter.
