Kernel Developer Hans Reiser to Speak at SVLUG

Why is Reiser4 50-100% faster than version 3? Find out at SVLUG.

Hans Reiser, architect of the Reiser filesystem and founder of namesys, will speak about the new version 4 of the ReiserFS at the Silicon Valley Linux Users Group's next meeting.

The meeting will be held Wednesday, November 6 at 7pm, at Cisco Systems, Building 9 in San Jose, California. The meeting is free and open to the public.

ReiserFS is one of several journaling filesystems available for Linux. Its key advantages include space efficiency, as it can pack several small files, or the tails of several large files, in a single disk block.

The SVLUG announcement for the talk reads, in part:

Reiser4 is the fastest Linux filesystem, performing 50-100% faster than ReiserFS V3. It performs all filesystem operations as atomic transactions and creates a foundation for a general purpose atomic transaction kernel API. It is built on a plugin-based infrastructure that makes it feasible to implement security attributes as just files with particular file features selected. It is highly scalable due to the use of per-node locking in its balancing operations. Like version 3 it stores small files space efficiently (packing them using database-like tree algorithms), but its performance is much higher when it does so.

Reiser4 employs dancing trees rather than balanced trees and rejects the BLOB approach, which may make the talk of interest to database specialists.

SVLUG is the oldest and one of the largest Linux user groups in the world, founded as the "PC-Unix SIG" three years before the first release of Linux.

Look for the first part of Hans Reiser's article, "Trees in the Reiser4 Filesystem", in the December 2002 issue of Linux Journal.

I've had some interesting experiences with ReiserFS. At one point I had a folder that was totally empty that occupied 12GB of disk space!! My home directory occupied about 20GB, even after I had erased everything in it. The only way to fix it was to erase the enired directory. I wonder if that happened to anybody else.

Must have been an old beta version are to be expected. I am running reiser on hundreds of machines some with multiple terrabytes of disk attached to each one and it really rocks. I have many terrabytes of reiser disk which has been running for a couple years now and it is great.

Every system i build i use Reiserfs for. It rocks!

did this system ever have windows on it?

I have a friends windows system that reports back that an 80 gig drive is 1.4 terrabytes. Very crafty/nasty windows virus and they just keep getting better.

Reiserfs is fast and reliable, its got my vote.

Someone thinks that once having a windows virus "on a
system" could cause reiserfs to waste space in a
directory? How can people be that stupid?

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
