Under funding by the U.S. Department of Energy YFS has developed an advanced implementation for clients and servers providing enhanced performance, functionality and performance. Later this year YFS will be announcing a line of storage appliances. Please feel free to contact me directly for more information. Jeffrey Altman President Your File System, Inc.

Take a look at http://openafs.org/ OpenAFS is based on the IBM/Transarc code and it is well maintained. They provide a list of companies that provide commercial support. There is also an AFS client included in the standard Linux kernel if that's of any interest. AFS is good at handling distributed reading of files that are not modified too much concurrently. It's probably not the fastest file system out there, but it's mature and OpenAFS supports a wide range of operating systems.

I don't recall seeing any such discussion; where did this happen? </pre> Jeffrey Hutzelman 2011-03-31T22:56:29 http://permalink.gmane.org/gmane.comp.file-systems.arla.general/1424 <pre>Hello all, I am writing to request some information regarding AFS and its current implementations. I hope this is the right list to ask. So my question is whether the latest versions of current AFS implementation still use 'afs' URI scheme. The 'afs' URI scheme can be found mentioned as reserved for further standardization in RFC 1738 (http://tools.ietf.org/html/rfc1738) dated December 1994, but there is no any definition of the scheme's syntax/semantics. Currently the 'afs' URI scheme is registered by IANA as Provisional with reference to RFC 1738. In the previous year there were some some discussions in the IETF regarding what should be done with it. However there was no consensus on any actions; two were proposed - move the scheme to Historical category or remain it as is. I'd like to hear the opinion of AFS experts.

Early registration ends April 20. Normal registration ends May 24. Late registration (after May 24) will be available on-site. Additionally, on Friday afternoon, there is an opportunity to visit Lowe's Motor Speedway to experience NASCAR driving. If we have 10 or more that commit to the racing experience, we will get a 10% discount. Options are either do the ride along which will cost $116.99 for several laps around the track or you can do the driving experience which will be a 3 hour training class which starts at 2:00 and then you get to drive around the track for 5 minutes for $331.99. The ride along starts at 3:00 on Friday. Here is the website if you want to check it out: www.nascarracingexperience.com.

I found some old instructions on building arla on MacOS, for use in a dmg. See below. Perhaps it can be helpful if you want to use more recent heimdal.

Regards, Mike </pre> Michael Meffie 2010-07-16T13:05:08 http://permalink.gmane.org/gmane.comp.file-systems.arla.general/1415 <pre> Hello, I have now tested Arla on Mac OS 10.6 also and the result was the same as for 10.5, that is if you install the binary package for 10.4 and update the kernel module it will work fine except for the shutdown bug. I used the same driver that I compiled for 10.5 for instructions see my previous mail. Only one small change was needed in the startup script for arla, chancge kextload to kextutil or remove option "-s". So the only thing that is left to solve is the shutdown bug. Bo Branten </pre> Bo Brantén 2010-07-15T18:25:50 http://permalink.gmane.org/gmane.comp.file-systems.arla.general/1414 <pre> A few aditional things: After ./configure but before make edit arla-0.90/include/config.h so it says: #define HAVE_OPENSSL 1 If using ./configure --with-krb5=/usr/arla instead of heimdal all the apps and libs compile clean and one don't need to install heimdal, this works fine on 10.4 and 10.5. When shuttding down the computer crashes as others has reported already on this mailing list, I don't think I have the knowledge to debug that problem so I leave it to others and continue to test on Mac OS 10.6 instead. </pre> Bo Brantén 2010-07-12T15:55:34 http://permalink.gmane.org/gmane.comp.file-systems.arla.general/1413 <pre> As has been reported here before the binary distribution of Arla 0.90 for Mac OS available on stacken works on 10.4 but on 10.5 one get an error on multiple symbols for some string functions when trying to load the kernel module so I tryed to compile arla myself on 10.5 and here is how it whent: Install the binary disribution for 10.4 (only the kernel module needs to be updated for 10.5) Install heimdal Install openssl in arla-0.90 run: ./configure --with-krb5=/usr/heimdal patch nnpfs/bsd/nnpfs_common.c: patch nnpfs/bsd/nnpfs_syscalls-common.c: &lt; #ifdef HAVE_KERNEL_KAUTH_CRED_GETUID --- &lt; #else --- &lt; #endif --- compile arla, nnpfs will be built, compiling apps and libs will fail but we only need the kernel module... sudo cp /Users/bobranten/src/arla-0.90/nnpfs/bsd/nnpfs_mod.o /usr/arla/bin/nnpfs.kext/Contents/MacOS/nnpfs sudo chmod +x /usr/arla/bin/nnpfs.kext/Contents/MacOS/nnpfs sudo /usr/arla/sbin/startarla ls /afs/stacken.kth.se/ftp/pub cat /afs/stacken.kth.se/ftp/pub/README It works!
