Is there any good literature explaining Linux's file system ?

[Rami Rosen]

Hi, Ruan,

AFAIK, there is no book which is dedicated to the Linux kernel
implementation of Linux filesystems.

In "Understanding the Linux Kernel, 3rd Edition"
By Daniel P. Bovet, Marco Cesati
rhere is one chapter (chapter 18) of about 40 pages about the
implementation of Ext2 and Ext3.
Please keep in mind that ext3 was removed:
https://lwn.net/Articles/651645/

There is also a chapter about Virtual File System (VFS), even though
you did not asked about it. I believe that learning about VFS is
important in ordet to understand how particular filesystems like
ext2/ext3/btrfs work.

See:http://shop.oreilly.com/product/9780596005658.do


Also in "Professional Linux Kernel Architecture" by Wolfgang Mauerer,
Wiley Publishing, Inc., there is a chapter about the "The Extended
Filesystem Family" (chapter 9), and also a chapter about VFS (Chapter
8).

here is also a book titled "Linux Filesystems Paperback"
by William Von Hagen. I did not read it. However, it is really old
(2002!); 14 years are significant in Linux development.

Good luck!
