Sine Nomine Associates' engineers Andrew Deason, Tom Keiser, Steven Jenkins and Mike Meffie are scheduled to speak at AFS & Kerberos Best Practices Workshop 2010 May 24-28, 2010 at the University of Illinois at Urbana-Champaign.
- Andrew Deason - libuafs: The coolest OpenAFS library you've never heard of
Imagine if you could run a fully-featured OpenAFS client without a kernel module, run multiple clients from the same machine, or even debug the Unix OpenAFS client as if it were a normal userspace program. Now, what if I told you that the code to do most of that is already available?
This talk will introduce the old and oft-forgotten libuafs -- the OpenAFS userspace client library -- to those not familiar with it. We will explore its many neat uses and potential uses, as well as its limitations, both temporary and intrinsic. We will discuss the past and current state of libuafs and its users, and the direction of its future.
I'll touch on the technical details of how libuafs actually works, and will give some quick examples/demos of some perl and FUSE bindings. I can also demonstrate specifically how libuafs has already been successfully used in testing OpenAFS for multiple-client scenarios.
- Tom Keiser and Steven Jenkins - Ubik Best Practices and Failure Modes
Ubik and the services built on Ubik are particularly important to the operation of a healthy AFS cell. This presentation gives a brief background on Ubik and then examines the Ubik-based services in OpenAFS, paying particular attention to "what can go wrong, why things go wrong, and how to handle failures?" in both the vldb and prdb, including a walkthrough of various utilities for checking the health of Ubik-based databases. Specific analogies will be made with RDBMS-based designs, which will help participants understand how many of the common problems relate to referential integrity and/or database replication management.
- Michael Meffie - AFS Tool Review
A variety of open source tools are available to AFS administrators to aid in monitoring, managing, and troubleshooting their AFS site. This talk will include a review of the tools which are available, including the tools provided with OpenAFS, contributed open source tools, and some works in progress.
