OpenAFS Newsletter, Volume 2, Issue 9, September 2010

Welcome to the September issue of the OpenAFS newsletter. This newsletter summarizes what is happening in the OpenAFS community.

As always, volunteers, patches, bug reports, or any other type of help is greatly appreciated.

Feedback on this newsletter is welcome. The goal is to summarize the various development efforts and news of OpenAFS for the community. Please let Jason Edgecombe <jason@rampaginggeek.com> know what you would like to see out of this newsletter. Any news about AFS-related projects is welcome and may be submitted to Jason for inclusion in the next newsletter.

The current and past issues of this newsletter are available at http://www.openafs.org/newsletter/

General OpenAFS Progress

The voting for the chairs of the afs3-standardization group is closed. Preliminary results show Hartmut Reuter and Doug Engbert as the two chairs of the AFS Protocol Standardization group. As the candidate with the most votes, Hartmut will serve a full two-year term and Doug will serve a one-year half-term. Official results will be confirmed later.

1.5.77 was released on September 8. It may be downloaded from http://www.openafs.org/release/openafs-1.5.77.html 1.5.77 includes some changes to the RPM packaging where the demand-attach and traditional fileserver binaries are both included in the same RPM.

The 1.6 branch was created in git on August 17. The 1.6 branch name is openafs-stable-1_6_x.

Marc Dionne verified that OpenAFS no longer produces lots of log noise in RedHat Enterprise Linux 6 Beta. https://bugzilla.redhat.com/show_bug.cgi?id=584901

Case Study - PDC

In this issue, I would like thank Harald Barth from the Center for Parallel Computing at the Royal Institute of Technology in Stockholm, Sweden for being profiled in the newsletter. --Jason

Jason: What is the name of your organization?

Harald: Our organization is the Center for Parallel Computing at the Royal Institute of Technology, Stockholm, Sweden. The swedish abbreviation is "PDC". The numbers given are for our center only because I do not have accurate numbers for other AFS cells at kth.se. There are at least 3 other AFS cells than pdc.kth.se at the Royal Institute of Technology.

Jason: What does it do?

Harald: PDC does provide High Performance Computing for academic users in Sweden and within joint projects within the EU.

Jason: How many users does your site have?

Harald: 1600, approx 250 active.

Jason: How many cells do you have?

Harald: pdc.kth.se. Some of the users have home directories in nada.kth.se.

Jason How many full-time and part-time people are responsible for AFS support and in what capacity?

Harald: First line helpdesk 1.5 persons, can give basic support. More complicated problems take part of my time.

Jason: How much data do you store in AFS?

Harald: 27TB

Jason: Do you use contractors or vendors to augment your workforce?

Harald: Rarely

Jason: How do you use OpenAFS?

Harald: All users have $HOME in AFS. AFS is used for all storage with the exeption of some HPC data which is in Lustre and some Cern Tier 1 storage which is in their storage solution.

Jason: What type of network bandwidth is there between your client and servers?

Harald: 1Gbit, starting to experiment with 10Gbit. But of course there may be clients somewhere else in the world with less bandwidth.

Jason: How many servers do you have?

Harald: Too few (as HPC researchers normally do not realize how much I/O their programs actually utilize). The current number is 12, hopefully more servers in the future, not to increase space but to increase throughput and availability.

Jason: Are they in different locations? How far apart are they?

Harald: Within the same building.

Jason: How spread out are your users? Same city, region, country?

Harald: Country. The size of Sweden/Europe RTT to the furthest users is around 15ms. Typical users are closer than 5ms.

Jason: Are your users spread all over Sweden? Europe? how many kilometers away are your users?

Harald: Most users are of course locally, but we have never restricted access from any other place on the Internet. As my users live and work over all of Sweden, they access their data from their desktop computers as well. Sweden is about the area and form of CA (slightly larger, but the extreme north of Sweden is not populated anyway ;-). It's approximate 900km from Stockholm to my most northern university users in Luleå. Other users in Europe are more rare, not because they can not access the data through AFS but because they normally use scp anyway.

Jason: Do you use any other network storage to supplement AFS, like dropbox, or windows shares?

Harald: Lustre, if a file system only visible within one cluster classifies as "network storage".

Jason: Is AFS the only networked filesystem that you use?

Harald: See above.

Jason: If not, what are the others, and how do they compare/contrast? Why do you use the other filesystems?

Harald: Lustre is in some aspects faster, but has by far not as good uptime as AFS.

Jason: Is your investment in AFS increasing or decreasing?

Harald: Increasing, but not as much as investments in Lustre.

Jason: Is there anything else that you would like to say?

Harald: Recently, PDC aquired a Cray cluster which runs some SuSE modified by Cray. It is our intention to bring AFS to that system, but so far we have not aquired enough information about the internal to make it happen.

Events

European AFS Conference

The European AFS & Kerberos Conference 2010 took place in Pilsen, Czech Republic, from September 13 to September 15. The conference was hosted by Centre for Information Technology, University of West Bohemia. The conference was friendly and well-organized.

A summary of the conference will be included in next month's newsletter. The slides are available at http://afs2010.civ.zcu.cz/agenda.php and the pictures are here: http://afs2010.civ.zcu.cz/download/afs-data/Gallery/Album/index.html

AFS Protocol Standardization

Informal drafts that haven't been uploaded to the IETF web site:

Rx Spec:

http://openafs.sinenomine.net/~mmeffie/rfc/draft-zeldovich-rx-spec-00.html

This draft is in the very early stages. Mike Meffie and Tom Keiser are the current owners of this proposal. A formal specification of Rx is needed as a basis for other IETF proposals.

Discussion on these proposals is welcome and should be done on the AFS3-standardization list at http://michigan-openafs-lists.central.org/mailman/listinfo/afs3-standardization

PTS Alternate Authentication

http://tools.ietf.org/html/draft-brashear-afs3-pts-extended-names

Status: Seventh Draft

Last update: August 31, 2010

I hope it's done.

The Kerberos 5 name type has been removed; The GSSAPI name type with the Kerberos OID will be used for all Kerberos 5 users. Consensus seems near.

--Derrick

AFS Callback Extensions

http://tools.ietf.org/html/draft-benjamin-extendedcallbackinfo

Status: Active - Waiting on RPC refresh

The callback draft is stable. There is a published implementation. My understanding is that it is accepted with the requirement that it be adjusted to use RPC refresh data types, which means AFSFetchStatus64 and the new 100ns time data type. This is regarded as "trivial" but at the same time, the spec can't be standardized as is. It is planned for merge in, IIRC, 1.9/1.10.

--Matt Benjamin

RXGK

http://tools.ietf.org/html/draft-wilkinson-afs3-rxgk

Status: Active

Rxgk is a security layer for AFS which will support strong encryption and authentication through Kerberos v5, GSI and any other GSSAPI security mechanism.

Changes which are considered suitable for the 1.5.x series are in git - look for changes with author sxw@your-file-system.com. A development tree, which will be frequently re-based, is at http://github.com/your-file-system/openafs-rxgk

Last Update: Jan 9, 2010

AFS3 ACL Rights

http://tools.ietf.org/html/draft-deason-afs3-acl-restrictions

Status: Second draft

Last update: January 13, 2010

We're waiting for the afs3-standardization structure to solidify before proceeding with this. So, no progress right now.

--Andrew Deason

Rx Security Object Providing Cleartext Peer Identity Assertions

http://tools.ietf.org/html/draft-tkeiser-rxrpc-sec-clear

Status: Third draft

Last Update: April 17, 2010

I released a new version of the Rx Clear security class I-D the other day. I am hereby soliciting comments on this new version of the draft.

http://tools.ietf.org/html/draft-tkeiser-rxrpc-sec-clear

The major changes in this version of the document are:

--Tom

AFSVol Tag-Length-Value Remote Procedure Call Extensions

http://tools.ietf.org/html/draft-tkeiser-afs3-volser-tlv

Status: Fourth Draft

Last Update: August 4, 2010

The other week I submitted a new draft to the IETF which implements the aforementioned changes (as well as a few others). The new draft is available at the following URLs:

The complete revision history is as follows:

Any comments or feedback are appreciated.

--Tom

AFS Byte-Range File Locking

http://tools.ietf.org/html/draft-mbenjamin-afs-file-locking

Status: Fifth Draft

This draft proposes protocol extensions to support byte-range and mandatory locking.

The first draft was submitted on May 5, 2010.

Projects

Demand-Attach FileServer (DAFS)

Project Contacts:

A fix for improving startup times with a large number of volumes was submitted to gerrit (2648), as have a couple of small fixes related to setting -vhashsize (2649, 2650). The fix for salvaging attached volumes (2329) and the fix to conditionally run fssync-debug (2480) have still not been merged, but getting them in will be worked on shortly. Some prerequisites for salvageserver improvements have been merged (2250, 1869).

--Andrew

Better Documentation

Project Contacts:

The 2TB partition limit was removed from the man pages for the 1.4.x series.

Per-File ACLs

Project Contacts:

I've re-activated this work over the past few weeks:

--Marc

Disconnected AFS support

Project Contacts:

Because Disconnected AFS will be built in by default in the forthcoming 1.6 release, this section will be dropped from future newsletters.

Encrypted Storage

Student Developer: Sanket Agarwal <sanket@sanketagarwal.com>

Mentor: Simon Wilkinson <sxw@inf.ed.ac.uk>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2010-March/017424.html

By the last newsletter, basics of chunking and extents had been implemented along with basic file functions of Reading/Writing/Moving/Removing and metadata file creation/deletion.

Present focus is to integrate the code with hcrypto library port in OpenAFS. As the port still dinkering in terms of usablity I am presently working on some working patches in gerrit to adapt my code to use the hcrypto library.

After this integration is complete, the task will be to manage user keys.

--Sanket

Mentor: Matt Benjamin <matt@linuxbox.com>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2010-March/017450.html

There still exists some issue where afsd fails to properly return the contents of the /afs dir when trying to view it. At the moment, progress has halted with that and I'm working on merging my changes with origin/master to push up what has been completed so far.
