    Release Notes: 1.7.2 is the recommended release of OpenAFS for Microsoft Windows users. Improvements include: speed (up to 800MB/second read throughput from SSD cache), a Loopback Adapter no longer needed, support for kernel-enforced Process and Thread Authentication Groups, new Explorer Shell integration, and AFS Mount Points and Symlinks which are filesystem Reparse Points. Some kernel panics have been fixed. For Unix, Linux, and MacOS X, the recommended production-ready release of OpenAFS is 1.6.0.

    •  19 Sep 2010 13:53

      Release Notes: For all systems, minor bugs were fixed, including Rx fixes and vos dryrun improvements. RXAFS_GetStatistics64 now returns statistics properly. For all Unix platforms, the cacheout program is now built, and a potential panic in bulkstatus is avoided. On FreeBSD, shutdown of the Rx kernel listener was fixed to avoid a potential dereference after it's gone. On Linux, the packaging was updated for the current configure options and built files. On MacOS, the DNS resolver is reinitialized on IP address change. On Windows, the software properly fails over to other replicas on bulkstat IO errors, and directory entry buffers are validated to avoid crashing the service.

        Release Notes: This release has Linux 2.6.34 support. There are Mac OS token interface fixes for 64-bit kernels on 32-bit hardware. A panic trying to get a slot for Volume information is avoided. Updated Mac OS binaries are available. If 1.4.12 works for you, there is no need to upgrade. RPMs requiring these updates will include them.

          Release Notes: This version is the recommended release for Microsoft Windows users. Non-Windows users should use 1.4.12. On Microsoft Windows, a race when updating cell vldb server lists that can result in a crash is now avoided. Integrated logon was enabled to work with Windows 7/2008 with a non-Domain Kerberos principal. For all platforms, the "vos setaddrs" command was added. The -expandgroups and -supergroups options were added to pts mem. On all server platforms, volume lock contention is avoided during DAFS startup. For all Unix client platforms, a FUSE afs client is provided. Updates were made for the FreeBSD 8.0 release. On MacOS, a Finder "Duplicate" failure is worked around.

            Release Notes: The Explorer Shell extension no longer crashes if symlink creation fails. krb5 error message translation was added. An SMB request trace facility is provided for debugging. Numerous DAFS fixes were made on all server platforms. There were also AIX fixes. On Linux, several changes were made for older kernels. Keyring destruction now cleans up all tokens. Keyring quotas are not enforced against root. On Mac OS X, a Growl client was provided for user monitoring of AFS events. Insert-only dropboxes are properly supported. Support for moving in Finder across mount points was added. The Preferences Pane now includes support for Kerberos 5 ticket renewal.

            I may have a look again some day but I can't hardly remember its good points! It's been a long time since 2002. I think that it is used in CERN right now

            As a contributor to the OpenAFS project, we welcome any and all feedback on it. I have personally added 28 new man pages to the documentation in the past two years. If you have any issues, please bring them up. Bugs go in the bug tracker and any questions can be answered by the helpful folks on the openafs-info mailing list. If you're confused or just lazy, contact me and I'll help you get to the right place.

            Welcome to the present
            While documentation is still OpenAFS' weakest point, this project has moved forward and is making great progress in addressing the outstanding issues.

            Re: openAFS documentation
            I have recently dived into OpenAFS and found the documentation to be amazing. This is a very high quality IBM documentation. You're right, the CD stuff is not up to date, but this is a complexe peace of software, and avoiding the documentation of such software is simply impossible. It aims complexe and heavy environement and therefor cannot be reasonably used with just a RPM. If you have already installed AFS environements in the pas you'll find the documentation to be actually easy to use. I've never done AFS installation before and yet, after two weeks, I had a very nice 12 servers using heavily AFS. Even today, and since AFS is complexe (not OpenAFS, AFS in general), I sometimes read some pieces of this huge 1000+ pages which, again, I consider to be a high quality documentation. there is no doubt for me it is much more important for OpenAFS, today (12/2004), to make OpenAFS better, rather than update here and there to wrong folders or CD stuff indicated in the documentation. I think there are less than ten opensource documentation like this in the world and the IBM fingerprint is clearly there. Make a small effort and you''ll see the only problem is that you have to follow, read, and understand the first server installation, as indicated in the documentation.

            In my experience, the documentation was quite good - yes, it did assume you were installing from scratch using a CD, but that just means that you have to actually think, instead of just following instructions. Also, I had to make use of the mailing list once - I got a response back within an hour that solved my problem.
