Why use reiserfs

ReiserFS is another filesystem common to linux systems, but with some ongoing codebase issues whereby it periodically tries to kill your wife. EXT3 file system is a journaled file system that has the greatest use in Linux today. It is the "Linux" File system. It is quite robust and quick, although it does not scale well to large volumes nor a great number of files. Recently a scalability feature was added called htrees, which significantly improved EXT3's scalability. I understand that Hans Reiser is in prison now Nobody even knows if the original developer for that FS is still alive Its performance doesn't scale well with multiple processing cores due to the specific implementation.

Prior versions were actually fairly prone to corruption and I've encountered this multiple times , though that's supposedly resolved in current versions. There are very few developers actually working on Reiserfs, which means that if and when problems occur, there's not much support to fix them.

Much of this information is from one of the head SuSE developers when they decided to switch their default filesystem from Reiserfs to ext3. There are non-technical reasons reiserfs is marginalized. It is not actively being supported as much as it used to be, especially with the founder leaving the project. With his conviction, there seems to have been no one to hold Namesys together, and previously, they had real problems trying to get Reiser4 in to the kernel, for a mix of political and practical reasons your bits need to fit the kernel coding style, for instance, and changing other things in the kernel is hard to get people to agree to.

It's a pity, as Hans was one of the few people who was trying for more than a better implementation of a POSIX file system, but it seems that Btrfs is taking up that torch. I've got machines on both reiserfs and ext3 and from a totally non-scientific observation of my recent personal usage, ext3 seems to suffer more than reiserfs. With reiser, I never had to rescue an un-bootable system whereas this has happened several times on ext3. I'd like to use ext3 for Linux but it borked out too many times for me.

The rupasov hash the default is the fastest, especially for extremely large directories with sequentially named files, but the drawback is that it has a higher probability of hash collisions. A hash collision means that the system will suddenly refuse to create a file with a certain name even if there is enough free space on the disk.

The tea hash is a cryptographic hash, but it is slower and has a lower probability of a hash collision. Since data retention should be of primary importance, I suggest using the tea hash, even if you do suffer a small performance hit for using it.

If you need to, you can also specify the block size after the device, but if you omit it, mkreiserfs will determine the best block size to use. Next, create the mount point. Conclusion Because the file system is such an important part of your system, you must take care when installing or updating anything related to it. Any mistakes may render your system inoperable or damaged. This is another reason why I encourage you to download or purchase the latest version of your favorite distribution, which most likely will have ReiserFS support already built in.

Nonetheless, the advantages of having a journaling file system like ReiserFS make the effort well worthwhile. With lightning-fast boot-up times and more reliable error recovery, ReiserFS is definitely a good choice. The time you would have spent doing an fsck on a GB ext2 partition compared to the time ReiserFS spends to check a partition of the same size will astound you.

Quite frankly, once you experience a journaling file system like ReiserFS, you'll never want to go back to something as slow as ext2. Editor's Picks. Linux kernel 5.
