[OpenAFS-devel] OpenAFS server 1.3.80 on x86_64

[Ulrich Schwickerath]

Hi, again,

sorry for the long period of silence from my side, I was mostly out of office 
this week, and only now managed to resumed working on this toppic. In order 
to exclude basic errors or errors introduced by third party RPM's I started 
from scratch on both a i386 and a amd64 system, both SMP running kernel 
version, and both reinstalled from scratch. Both nodes are AMD Opteron nodes. 
The operating system is SL303, and the kernel version 2.4.21-20.ELsmp. I 
started with the original tar balls from open IB (version openafs-1.3.80), 
and did a basic configuration aka
./configure --enable-transarc-paths
make
make dest
repeating the same step on both nodes. While it works on the i386 system, I  
reproduced the reported problem on the 64bit Opteron node, that is when 
trying to start the client without -dynroot it gets stuck (although the 
root.afs and root.client volumes are  there) , if using -dynroot afs is 
mounted, but if I try to access it eg. with fs, fs itself gets stuck 
(previously I evens saw a segfault at this step but no oops in the syslog 
which I could send you). So, I think there is definitely problem for Opterons 
on 64bit. I can live running the box with i386 system on it, and that is most 
probably what I'm going to do now, but if there is any more piece of 
information that I can send to you to be able to investigate the problem 
please let me know. It would be really nice to find a solution for this :-)

Many thank's for all the tipps that I got from you!
Ulrich
