[OpenAFS] Crash testing OpenAFS
Mon, 15 Aug 2005 10:36:34 -0700
At the Workshop the MIT presenter stated that AFS worked fine until it was
"placed under load".
In the process of copying files from a 1.2.11 box to a 1.3.87 box I ran into
the same problem with Linux 2 Linux copying. That's how all this started.

by "destination" you are referring to the afs fileserver containing the
destination afs volume?

if my assertion is true, then you should not be running anything on the
console, this includes x-windows or any other pretty graphical gui. if the
server crashes, then you will be able to see the panic/oops unless the
machine wedges in which case we have to try something else.
try the simply things first though.

you keep saying your cache gets corrupted. this leads me to think that your
afs client machine is crashing and not the afs file server.
>>I suspect the Linux AFS 1.3.87 client crashes on the 1.3.87 server but I
don't have the expertise to tell. The cache corruption may be caused by the
is the fileserver and client the same machine?
>>There are 2 client/fileservers a 1.2.11 and a 1.3.87. The 1.3.87 box is
the destination that crashes.
how about that network diagram?
