Resources

ReiserFS is a journaling filesystem for Linux licensed under the GPL-2 license and is the predecessor of Reiser4. ReiserFS was originally developed by Namesys and Hans Reiser, but is under maintenance by volunteers nowadays.

Installation

Kernel

Important
ReiserFS is scheduled for deprecation in kernel 5.18 and eventual removal in 2025[1]. Because of this, migration away from ReiserFS is encouraged and newly created file systems should be avoided.

Support for ReiserFS has to be enabled in the Kernel first.

Emerge

Utilities for ReiserFS are available in sys-fs/reiserfsprogs package:

root #emerge --ask sys-fs/reiserfsprogs

Troubleshooting

ReiserFS filesystem corruption issues

If the ReiserFS partition is corrupt, try booting the Gentoo Install CD and run reiserfsck --rebuild-tree on the corrupted filesystem. This should make the filesystem consistent again, although there may be some lost files or directories due to the corruption.
