    This presentation will introduce the deployment status and activities of AFS at IHEP. AFS (Andrew File System) is a distributed file system that provides namespace architecture aimed at dispersed computing environments and a set of tools geared toward ease of use and manageability. AFS was firstly deployed in IHEP 10 years ago, which worked as home directory for all users in IHEP. During...

    Jeffrey Altman (Your File System Inc.)
    26/03/2014, 15:00
    Microsoft Windows differs from UNIX/POSIX in significant ways with regards to the management of directories, symlinks, mount points (aka junctions) and file system object metadata. This talk will describe the design of the OpenAFS Windows client with a focus on reparse points and path processing. The real world designs of publicly visible cells will be examined with a focus on those that...

  13. 10. AFS Performance
    Simon Wilkinson (Y)
    26/03/2014, 17:00
    Many users, administrators and developers have observed that OpenAFS scales badly on multi-core machines. On some platforms we not only fail to take advantage of additional cores, but run slower than we would on an equivalent single core machine. This talk will examine the reasons for this. We will present recent work profiling the AFS server suite and discuss ways of using this information...

  14. 14. OOB Update
    Mr Andrew Deason (Sine Nomine Associates)
    26/03/2014, 17:30
    In 2012, I presented about the prototype "Out of Band" project, a project to allow OpenAFS bulk network communication over protocols besides Rx/UDP (such as TCP). Per the original plan, OOB has since been partially redesigned in order to address shortcomings in the original design. This new implementation fixes various problems, allows OOB to be more easily used for other arbitrary...

  15. 21. AFS-OSD current state and future
    Hartmut Reuter (M)
    26/03/2014, 18:00
    AFS-OSD is currently used at two sites with totally more than 1 PByte of data. Some fileservers are still openafs 1.4 based, others already 1.6 based. The 1.6-based source is kept in github. For the integration into openafs 1.9 a stripped version is being prepared for openafs's git master which is compatible to the 1.6 version in github, but not to the old 1.4 based clients and servers.

    Jeffrey Altman (Your File System Inc.)
    27/03/2014, 09:00
    An overview of the major changes in the Heimdal 1.6 release series. A discussion of the problems experienced in Heimdal 1.5 when sites attempted to upgrade AFS cells to use non-DES keys.

  18. 34. rxgk status update
    Benjamin Kaduk (Massachusetts Institute of Technology)
    27/03/2014, 10:00
    Talk
    Kerberos
    A status report will be given on the standardization process for the rxgk security class and its use with the AFS-3 protocol, and the implementation and use of rxgk in OpenAFS. Numerous internal updates and additional features are needed in the OpenAFS codebase in order to make full use of rxgk universal, and these will be discussed as well.

  19. 18. Deploying Secure NFS v3 / v4 in a Large Enterprise
    Moritz Willers
    27/03/2014, 10:30
    The talk will share our experience of deploying Secure NFS v3, Secure NFS v4, as well as just NFS v4 throughout a large enterprise with hundreds of NAS appliances and thousands of hosts. The NAS appliances are NetApp filers and the clients are mainly RedHat Linux systems; the problems encountered with the NFS v4 protocol however are not Operating System specific. The challenges of managing...

  20. 9. The Road to IPv6
    Simon Wilkinson (Y)
    27/03/2014, 11:30
    Many individuals have expressed interest in IPv6 support for AFS, although it has never reached the top of the development priority list. This talk will discuss the necessary protocol and code changes to support IPv6 across the AFS suite, highlight some of the more challenging areas. We will detail the progress that has been made in producing an IPv6 capable RX library, and rxperf test application.

  21. 12. OpenAFS and IPv6
    Mr Andrew Deason (Sine Nomine Associates), Mr Michael Meffie (Sine Nomine Associates)
    27/03/2014, 12:00
    Institutions and businesses are increasingly mandating IPv6 compatibility from their networked applications and systems. The day is approaching when OpenAFS must be able to work with hosts that exclusively use IPv6 addresses. This involves a variety of changes to the OpenAFS codebase and how OpenAFS operates over the wire. This talk will identify the areas where the work to implement IPv6 is...

  23. 13. AFSmin - an AFS dashboard
    Mr Michael Meffie (Sine Nomine Associates)
    28/03/2014, 09:00
    Many sites have created site-specific AFS dashboards for their administrators and to address their site-specific needs. In this talk, I will present AFSmin, an open, redistributable dashboard solution that anyone in the community can use. AFSmin is a work in progress, open source AFS dashboard, featuring a modern UI and easy setup. It can be used for basic monitoring and basic AFS...

  25. 11. AFS Salvager and Large Volumes
    Mr Mark Vitale (Sine Nomine Associates)
    28/03/2014, 10:00
    The AFS salvager is one of those programs (like the restore part of backup/restore) that are only needed when something has already gone wrong, and must be set right as quickly as possible. In a perfect world, there would be no need for recovery tools like the AFS salvager; servers would always come down cleanly, and filesystems would always be in a consistent and correct state. But we...

  26. 15. Getting started with AFS code
    Perry Ruiter (Sine Nomine Associates)
    28/03/2014, 11:00
    Anyone currently administrating AFS who wanted to “look under the hood/bonnet” as it were, will find this review of some the hurtles encountered getting started supporting AFS code helpful. Where is the code, how do you build from the source, simple debug techniques and how to develop/apply a test fix and eventually pushing it upstream will be covered. To drive AFS adoption going forward, the...

  29. 26. Accessing AFS through the s3 protocol & A glance at RestFS
    Mr Fabrizio Manfredi (-)
    28/03/2014, 12:30
    The myS3 permits accessing to AFS cells from everywhere with a simple S3 client or an http request. The main function of myS3 is the conversion of the S3 requests in local filesystem requests. This solution has many advantages like: multi platform and multi device ( s3 clients exist for everything), not intrusive ( no kernel module is required on the client side), standard port used (http...
