Subject: 2007 Linux Storage & Filesystem Workshop


The submission date for the Linux Storage and Filesystem Workshop is
coming up quickly, and it would be good for ext4 to be well-represented.

Workshop Organizers

Program Chair
Ric Wheeler, EMC

Valerie Henson, Intel
Andrew Morton, Google
Trond Myklebust, Network Appliance
Brian Pawlowski, Network Appliance
Theodore Ts'o, IBM

Overview

The Linux Storage and Filesystem Workshop is a small, tightly focused,
by-invitation workshop. It is intended to bring together developers and
researchers interested in implementing improvements in the Linux
filesystem and storage subsystems that can find their way into the
mainline kernel and into Linux distributions in the 2--3-year
timeframe. The workshop will be two days, the second day overlapping
with FAST '07 tutorials. The workshop will be separated into storage and
filesystem tracks, with a combined plenary session.

Topics and Submissions

Researchers and developers who are interested in attending should submit
a 2--3-paragraph position statement that describes the topic or topics
they would like to discuss during the workshop, and whether such a topic
would suit the filesystem track, the storage track, or the plenary
session. Examples of topics of interest include:

* New trends in storage technologies likely to impact Linux in the
next 3--5 years
* More realistic methods of measuring filesystem and storage performance
* Proposed improvements to Linux filesystems, including, in particular:
o Handling of storage errors
o Filesystem repair techniques
o Scaling to very large (terabyte) filesystems
* Progress reports on implementation of features discussed at the
Portland Filesystem Summit
* Changes to the interface between the operating system and storage devices
* Proposed improvements to existing Linux storage subsystems,
particularly with an emphasis on:
o Refactoring common code out of storage subsystems and into
the block layer
o Better robustness and error recovery
o Barrier implementations in the face of TCQ
o Making use of storage capabilities (such as block guard or
non-power-of-2 block sizes) for novel filesystem and
application features
* Progress reports on implementation of features discussed at the
Vancouver Storage Summit
* Userspace tools for managing storage systems (including better
presentation to the user via sysfs)
* Storage futures, including:
o New transports
o Changes to existing standards for new storage features
o SAS/SATA convergence
o Do we yet have a use for Object-Based Storage Devices (OSD)?

Just another reminder - please do send in a submission if you want to
attend. If you cannot send in a submission by the 24th, you can contact
me or someone else on the program committee and we can help.

Thanks!

Subject: Re: 2007 Linux Storage & Filesystem Workshop

We are two students from the University of Cordoba, Argentina,
studying Computer Science. We are taking a second year course named
Operating Systems, in which we study, well, basically, Andrew
Tanenbaum's "Modern Operating Systems" (2nd Edition).
We also have a programming-related lab, in which we've worked in
several areas, such as managing processes and threads -work with race
conditions, semaphores, mutexes, etc- (all done in linux, obviously),
wrote a little baash-like command interpreter, and a memory manager to
understand how bitmaps work, and the different algorithms to optimize
memory managment.
For our last project we were asked to write a paper on a subject of
our choice. After looking though a few possibilities, we chose to do
it about linux Ext4. We've been asked to not only compare it
(performance-wise) with Ext3, but to explain -and try to justify the
results of the benchmark comparisons- the following: caracteristics of
each file system, internal arquitecture, and disk structure. Doing
research, we've found little information related to these subjects,
and just read this email, which seems to be highly related. If anyone
could direct us to some good reading on the subject, or knows about
this, we would apreciate it very much.
Thank you very much for your time!
