The Reiser File System (reiserfs)
The Reiser File System (reiserfs)
The other popular journaling file system for Linux is the written-from-scratch Reiser file system, reiserfs. For a long time it was used by the SUSE distribution, but SUSE now uses ext3. reiserfs offers similar features to ext3, but there is no easy migration path from an already existing ext2 partition. In the past, reiserfs didn't work well over NFS mounts, but recent versions of the nfsd daemon have fixed those problems. Fedora does offer reiserfs, but does not offer support for booting from it as the root partition file system, nor does it offer the choice to format non-root partitions as reiserfs during the installation process.
reiserfs is offered primarily for compatibility with existing reiserfs partitions you might want to access. Although the Reiser file system can be used as a root file system (meaning that Linux can be booted from a Reiser file system), Fedora has chosen not to support that option. The main problem is that reiserfs does not, at the time of writing, play nicely with SELinux and is therefore not recommended either by Red Hat or the NSA (SELinux's developers).
NOTE
Namesys, the company behind reiserfs, has struggled since its founder (Hans Reiser) was arrested as part of the police investigation into the murder of his wife. Few distros now recommend using reiserfs, so we would recommend avoiding it for the foreseeable future.
