[OpenAFS-port-darwin] Disk error leads to OpenAFS problems?

[Samuel Bayer]

All -

I've been having substantial trouble with OpenAFS on my dual G5. For 
quite a while, I thought it was OpenAFS itself, but lately I've been 
suspecting that the problem lies in my computer itself. For instance, I 
can't run 1.4.1-r6 under Tiger on my computer without encountering 
problems almost immediately (got a random lock which hung AFS), but I 
was able to run it without incident, using it fairly heavily, on a 
different dual G5 with a clean installation of Tiger. Under Panther on 
my machine, I encounter cache corruption; e.g., the first few characters 
of a file will appear to contain the volume name rather than the 
appropriate contents of the file. I don't think anyone else at my site 
has encountered this problem.

I've run a variety of hardware tests on my computer so far: the extended 
hardware test on the boot CD, and a third-party application called 
memtest. So far, I haven't found any memory errors, although I expected 
that would be the problem; however, the extended hardware test *did* 
find a disk error.

My question is: could a disk error cause the problems I've been having 
with OpenAFS?
