getting nnpfs into the mainline kernel?


Hello,

I would like to ask if there has been any discusion on trying to get nnpfs 
into the mainline Linux kernel?

It is hard work to maintain an fs outside, if its in all small changes 
will be done by the person responsible for introducing them.

Note about testing Arla


With my patch reading files from AFS works well on all Linux kernels from 
v2.6.3x to v4.5.

To test Arla you typically install Arla 0.90 (because arlad in CVS is 
works in progress) but you apply my patch to get the latest nnpfs.

Writing files to AFS has some old bug from between 2.6.22 and 2.6.24, I 
will look in to it when I find the time.

Bug found in Arla CVS


Hello,

when testing Arla I found a bug in the CVS version that I thought I should 
warn you about:

In the CVS version they changed from uppercase to lowercase file and dir 
names in the cache:

PATCH: Arla 0.90 on Linux 2.6.34 to 3.5


Hello,

I have done some work to update arla for Linux, the changes in the kernel 
are so big that it must be done stepwise so to begin with I try on Ubuntu 
12.04 LTS and I have created an patch for the kernels 2.6.34 (witch is 
were we stopped working in 2010!) to 3.5. (Note that if you try arla on 
Linux use arlad from the 0.90 distribution and the latest nnpfs)

arla cvs checkout


Hello,

it was a long time since anyone worked on the Arla project but I noticed 
it is not so easy to get the current source code from CVS at stacken so I 
created a mirror that can be helpful to somebody:

All,

 

Thank you all for your kind /prompt responses.  I am all set, no need for any more info.

Subject: Looking for AFS Information

 

Hello,

 

I see that Arla is a project that studies Andrew File system and it appears that you have implemented in your university?   Is this a project that still active at your university?    I am trying to find out if there are any vendors (or open source) that have taken  AFS and make it a product.    My understanding is that a while back IBM had purchased Transarc  but there is no support for that anymore.   

 

I am looking for file systems products that can provide access to global data (flat files) efficiently in an optimized way, in real time; the clients can be sitting in multiple geographic locations.    I thought to write to you since seem very familiar with AFS and  perhaps can you provide me with names or refer me to someone   else that can help me pursue this.

 

Thanks for your help in advance!

AFS and 'afs' URI scheme

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.

Thank you in advance,
Mykyta Yevstifeyev
