Welcome to the Reiser4 Wiki, the Wiki for users and developers of the ReiserFS and Reiser4 filesystems.

For now, most of the documentation is just a snapshot of the old Namesys site (archive.org, 2007-09-29).

There was also a Reiser4 Wiki (archive.org, 2007-07-06) once on pub.namesys.com.

Stable patchsets

As reiser4 is still not in mainline, Edward Shishkin is kind enough to provide patches for the stable version of the Linux kernel.

Standalone reiser4 tree

According to Reiser4 Upstream Git Repositories on GitHub, this is how the the standalone tree can be used.

Download the latest Reiser4 kernel patch and patch the kernel:

wget https://sourceforge.net/projects/reiser4/files/reiser4-for-linux-4.x/reiser4-for-4.7.0.patch.gz

cd /usr/local/src/linux-git
git checkout -b local-4.7 v4.7
gzip -dc ~/reiser4-for-4.7.0.patch.gz | patch -p1

Replace fs/reiser4 with the standalone version:

rm -r fs/reiser4
cd ../

git clone https://github.com/edward6/reiser4 reiser4-git
cd reiser4-git/
git archive --format=tar --prefix=reiser4/ HEAD | tar -C ../linux-git/fs/ -xvf -

Be sure to adjust the directories as necessary on your system!

With that, we should be able to build the kernel now:

cd ../linux-git/

Distribution packages


openSUSE is building reiser4 packages too:
