Reiser4

Reiser4 is computer file system, a new version of the ReiserFS file system, written from scratch. It has following advanced features:

• efficient support of small files,
• handling of large and very large directories with hundreds of millions of files,
• flexible plugin infrastructure,
• atomic file system modification,
• efficient journalling through wandering logs,
• dynamically optimized disk-layout (through allocate-on-flush, and online repacker), and
• the integration of meta-data into the file system name-space.
