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.
ReiserFS is scheduled for deprecation in kernel 5.18 and eventual removal in 2025. 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.

Utilities for ReiserFS are available in sys-fs/reiserfsprogs package:
emerge --ask sys-fs/reiserfsprogs
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.
- Ext4 — an open source disk filesystem and most recent version of the extended series of filesystems.
- XFS — a high-performance journaling filesystem
- ZFS — a next generation filesystem created by Matthew Ahrens and Jeff Bonwick.
